  2. Internal Server Error: This error indicates a problem with the server, preventing the website from loading.
  3. Error Establishing Database Connection: This error occurs when Drupal cannot connect to the database, usually due to incorrect login credentials or a corrupted database.
  4. Page Not Found: This error appears when a page or content has been deleted or moved, and the website cannot find it.
  5. Access Denied: This error occurs when a user does not have the necessary permissions to access a specific page or content.

To troubleshoot and solve these errors, here are some tips:

    How can I fix a Drupal site that is showing long lines of text and limited HTML tags?

    To fix this issue, switch to the “Full HTML” input format in the menus administration screen and enable the URL Filter and Code Filter modules. This will allow for more HTML tags and prevent long lines of text from appearing.

    What should I do if I accidentally turned on Site Maintenance mode and can’t log in to my Drupal site?
