# Error in additional CSS (WordPress 6.0)

 * Good evening,
 * I am a teacher, amateur Web Developer, and I want to mention a very serious problem
   that has to do with the additional CSS of my business website (wordpress, appearance-
   > additional CSS). While typing the desired CSS (and the changes are correct 
   in the preview) I click on the “Publish” option, but the changes are not stored/
   saved and when I go back to the CSS editor there is none of the changes/additions
   I made. I have been entering CSS for several years and that has not happened 
   again. WordPress version and all my plugins are up to date.
 * In order to correct the problem:
 * 1. I turned off a lot of plugins for the case of a conflict. I avoid turning 
   off everything, because a lot of things will ruin the website and I’m afraid 
   I will have to reconfigure everything again from scratch. I am thinking of doing
   this as a last option.
 * 2. I tried all the browsers, cleaning their cache.
 * 3. I cleaned the WordPress cache.
 * 4. I made sure I typed CSS correctly.
 * None of them worked. I searched similar cases in other forums, but nothing worked.
   Here I mention that [the theme of my website](https://bizzthemes.com/themes/bizznis/)
   is not been upgraded for several years and its company will obviously not be 
   involved with it again. So, is this a theme problem? This would be a very nightmare
   scenario, as I may have to make my website from the beginning with another theme.
   Thanks in advance for any advice.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Ferror-in-additional-css-wordpress-6-0%2F%3Foutput_format%3Dmd&locale=en_US)

 * If the memory limit is exhausted then this issue can be faced. Although that 
   could be one of the reason. Please see if you are getting any errors in your 
   dashboard or in error log and then try adding following in wp-config.php file
   and then try saving the CSS again.

 * Unfortunately the same problem again. With the debugging mode enabled, the message
   I get is:
 *     ```
       Notice: The add_submenu_page function was incorrectly called. The seventh parameter sent to add_submenu_page () must be an integer that represents the position of the menu. Please see the Debugging in WordPress page for more information.

       DEPRECATED: Hook contextual_Help is obsolete by version 3.3.0 onwards! Use Get_Current_screen ()-> add_Help_tab (), get_current_screen ()-> remove_help_tab () instead. in /var/www/vhosts/efthimistzimos.sites.sch.gr/httpdocs/wp-includes/functions.php on Line 5754

 * Also, let me mention that the problem only occurs in child theme. If I change
   to parent theme, everything works normally.
