    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?
