How to resolve the error: SoftException in Application.cpp 267 File /home/public_html/index.php is writeable by group

Sun, 15 Dec 2024 00:00:00 +0000

The error “SoftException in Application.cpp:267: File ‘/home/username/public_html/index.php’ is writeable by group” frequently occurs on servers using cPanel, especially when the environment is configured with the suPHP PHP handler. This handler requires strict permissions for files and directories, and excessive permissions can trigger security errors.

In this article, we cover how to identify and fix this problem using chmod and chown, common tools for managing files and permissions in Linux.

Understanding the SoftException in Application.cpp error

Inappropriate Permissions: Files configured as group-writable (for example, with permissions 0666) pose a security risk and are not supported by some environments configured with suPHP or other security restrictions.
Incorrect ownership: If files are not assigned to the correct user, this can also lead to permission conflicts.
Server Configuration: Changes to the PHP handler (from DSO to suPHP) make permissions stricter. In suPHP, files need to be owner-readable and write-safe by third parties.

Resolving the SoftException in Application.cpp error

Some ways to resolve the SoftException in Application.cpp error include:

What is HTTP Session

Sat, 12 Aug 2023 00:00:00 +0000

An HTTP session is a sequence of network request-response transactions. When a user logs into a web application, for example, an HTTP session is created to keep track of the user across multiple requests.

Session support allows you to register an arbitrary number of variables that will be preserved between requests. Each new visitor to your website receives a unique identifier, called a session ID. This is saved in a user-side cookie or propagated via URL.

Increasing the Memory Limit in PHP for WordPress

Sun, 18 Jun 2023 00:00:00 +0000

Since WordPress is a CMS (Content Management System) with the possibility of using external themes and plugins, it is common for some errors to happen after the installation, even for testing, of a new extension of this nature on your site.

It is also susceptible to some errors when a PHP or Apache or Nginx version upgrade occurs, due to the complexity of keeping all these plugins and themes up to date and with compatibility with the most current versions of these softwares.

Executing protected and private methods in PHP

Sun, 18 Jun 2023 00:00:00 +0000

Private and protected methods should not be accessed outside the permissible scope of class or subclasses. But there are some situations where this is necessary, for me in some contexts of automated testing (unit or integration), or in others where I am implementing a feature and want to perform punctual executions to verify behaviors.

Regardless of why, and the good practice guideline in which I would claim, do not call private or protected methods outside of their scopes, several languages provide support for this possibility.

GIT - Semantic Commits

Fri, 26 Nov 2021 01:40:21 +0000

What are “semantic commits” or “conventional commits”

Semantic Commits, also known as conventional commits, are the best way to document your implementation of applications, as you check context to the management of change of your source code. Semantic commits are considered good practice in the use of GIT as much as other VCs (code versioning systems).

Why to use semantic commits

You should write in a GIT commit message not only what you have done, but also specifying WHY you have done that.

How to resolve slow Git conections with SSH in Github, Gitlab or Bitbucket

Wed, 17 Nov 2021 19:13:09 +0000

To fix push and pull slow GIT commands, when we are using SSH keys with the Github, Gitlab and Bitbucket repository services, you need to change the IP version setting used.

I allways use the HTTPS connections of the source codes repository services, especially for the practicality of using services on any machine without the need to create SSH keys to the GIT connection.

However, the connection speed has become a problem, especially after Github and Bitbucket forcing interaction with their repositories through SSH keys.

How to fix Eslint's error ‘Unexpected string concatenation’

Thu, 28 Oct 2021 23:43:35 +0000

By executing ESLINT in a JavaScript code, Nodejs or Expressjs, we can find the error “unexpected string concatenation” or “Unexpeted String Concatenation”.

This lint points to a possible code that manipulates string concatenation, which was written in order to result in a difficult reading.

Solving the Eslint error “Unexpected string concatenation”

In addition to being able to change your LINT configuration to correct the error “Unexpeted String Concatenation” when using Eslint as the linter in our JavaScript project, we should use https://developer.mozilla.org/en-us/docs/web/javascript/reference/template_litals “target =”_ blank “rel =“noreferrer noopener”>Literal template (model literals) instead of straight string concatenation.

Open data repositories for developers

Thu, 02 Sep 2021 00:00:00 +0000

Awesome Data Table References

Awesome Data Table References is a repository of my responsibility, where I curate references to open data tables from Brazilian and world institutions.

Whenever it is necessary to create a field of choice of municipalities, Brazilian states, search for zip code, identification by race or color, developers find themselves by building this data manually, often with various codes of base registration tables.

Currently the repository provides data files to download in original CSV, XLS, SDG, XML or JSON versions.

Domain extensions to use in local development

Tue, 31 Aug 2021 14:57:54 +0000

The .dev extension is no longer a local domain option to use in your application development configuration, what would be the best domain extensions to replace dev?

Since version 63 of the Chrome web browser (released in December 2017), the same force all domains ending in dev (and .foo) to be redirected to https by means of a pre-loaded HTTP Strict Transport Security (HSTS) header.

From July 2018 Firefox also started this forced redirection to the HTTPS .DEV domains.

Routing in Laravel does not work

Sat, 14 Aug 2021 00:12:45 +0000

This article deals with the Laravel routing not to working in new projects, taking into account a very specific context, when you have new Apache server installations.

Problem script

At some point you will start a new project with the newly installed project with the Laravel Framework, after running the standard command to create a new composer project:

composer create-project laravel/laravel  --prefer-dist

All dependencies downloaded and loaded by the compose, hosted permissions on the storage and bootstrap/cache folders, so to start the work you enter a test route and a checking controller, and here’s the error 404 (File Not Found) is returned.

Install (deploy) Laravel PHP application in subdirectory with CPanel

Mon, 28 Jun 2021 23:58:36 +0000

If you work with the PHP Framework Laravel, you know that installing your application in a default directory of a VPS account or a shared server, without changes, will force you to run the application leaving the root directory as it will need to access it by the subdirectory /public. For example: http://mydomain.com/public

In case of access to the root directory, in this example, the Laravel program PHP files will be exposed and accessible, including your setting file of environmental variables: .env, with database keys and passwords and APIs services.

How to fix the “Target Class [Controller] does not exist” error in Laravel 8

Wed, 24 Mar 2021 10:08:00 +0000

The Laravel 8 framework brings a series of new features, improvements in known functions and some structural changes. One of these changes was the removal of the standard “Namespacing”, so it has generated some confusion and the “Target Class [Controller] not exist” error.

This change is compatible with previous versions, which means that older projects that used Laravel 7.x can easily migrate to Laravel 8.X, without changing anything because the basic structure of [its components](/componentsFramework-Laravel Architecture/) is maintained, but new projects created in Laravel 8 should take this into consideration.

What's New in Laravel Version 8 Release

Tue, 08 Sep 2020 22:38:51 +0000

Laravel 8 has been released and includes many new features such as Laravel Jetstream, a unique directory for models, model factory classes, migration squashing, improvements to quota limitations (rate-limit), helpers for testing dates and time, dynamic blade components, and many other features.

Before we continue the article with the new features of version 8, remember that starting from version 6, Laravel follows SemVer (Semantic Version) and releases a new major version every six months.

What is the HTTP protocol

Mon, 03 Aug 2020 11:00:12 +0000

We can say that HTTP network protocol highway that sustains all the communication and operation of web systems and the communication of APIs REST or SOAP between mobile applications and backend servers.

In other words:

Virtually all information on the Internet travels using the HTTP communication protocol

Mazer Junior, A.

What is HTTP

HTTP is the acronym for Hypertext Transfer Protocol. It is a network communication protocol used to exchange information between systems (applications) that allows data transfer between computer networks, being the main protocol for the development of web systems.
