1.Error ‘403 Forbidden’ in WordPress.

error 403

Error ‘403 forbidden’ is one of the most common and dreadful errors in WordPress that can come across at one point or another.

One of the primary causes for this error in WP is because of imperfectly installed or configured security plugins. Some of the WP security plugins block IP addresses if they suspect them to be harmful. Another possible reason can be incorrect file permissions on the server and .htaccess file.

Solution for Error Caused By WP Plugins

  • First of all, temporarily deactivate all WP plugins available on your site, including the security plugins.
  • Check if it is resolving your issue. If your issue gets resolved, it simply says one of the WP plugins was responsible for this error.
  • To find out the plugin responsible for the error, activate all plugins one by one until you don’t reproduce the ‘403 forbidden’ error again.

Solution to Error Caused by .htaccess file

  • First, connect to your site using the file manager or FTP client in cPanel. Now look for the .htaccess file in the root folder.
  • Download this .htaccess file to your computer so that later on you can take a fresh backup of it.
  • Now delete this file from your server. Access your site and see if the error is resolved. If yes, now you can create a new .htaccess file from your WP admin area.

2.WordPress Automatic Logout Issue

WordPress sets a cookie in your browser to authenticate a login session. This cookie is set for the WordPress URL stored in your settings section. If you are accessing from a URL that does not match the one in your WordPress settings, then WordPress will not be able to authenticate your session.
The WordPress URL and the Site Address are two different URLs (notice one has www. and the other doesn’t).

A simple fix for this login issue is to make sure that you have the same URL in your Site Address and WordPress Address fields in your WordPress settings. This means that you need to choose either www or a non-www URL in the both fields.

Login to your WordPress dashboard and go to Settings » General.
If you can’t access the admin area, then you can update these fields by editing the wp-config.php file.
Connect to your website using an FTP client,and locate the wp-config.php file in your site’s root directory. You need to download this file to your Desktop and open it in a text editor like Notepad. Add this code just above the line

 1 define(‘WP_HOME’,’http://example.com’);
2 define(‘WP_SITEURL’,’http://example.com’);


If you prefer to use www in URL, then use this code instead

1 define(‘WP_HOME’,’http://www.example.com’);
2 define(‘WP_SITEURL’,’http://www.example.com’);

3. 503 Service Unavailable Error

 503 Service Unavailable Error

This error usually occurs when your web server is not receiving a proper response from a PHP script. And this PHP script can be your WP theme, plugin or custom code snippet.

To fix it, we will disable all unnecessary PHP scripts one by one until the error is resolved.

All your WP plugins are PHP scripts so you can deactivate them.

Since you can’t access your site directly because of the 503 error, you will have to connect to your website through an FTP client or File Manager in cPanel.

Once you’re connected, look for the WP root folder, it will be named as public_html. Open this folder and go to the wp-content directory. Now find the ‘plugins folder’, do right click and rename it. You may give it the name ‘plugins deactivated’ or whatever you like.Now access your site, see if the error has resolved. You should be able to visit your WP site if the plugin was behind this error. By replacing the name of your WP plugins directory, it automatically deactivates all of your plugins.

Now you need to correct the name of your WP plugins directory back. Change your plugins name back to its actual name i.e. plugin. This way WP will recognize all your old plugins, but they will be inactive by default.
