 * Hello. My question is related to incompatibility report generated by PHP Compatibility
   Checker for the TablePress plugin I use on my website. The plugin is at its latest
   version 1.12. When I ran the check for compatibility with PHP 7.3 there are four
   warnings as follows:
    993 | WARNING | INI directive ‘mbstring.func_overload’ 
   is deprecated since PHP 7.2 997 | WARNING | INI directive ‘mbstring.func_overload’
   is deprecated since PHP 7.2 1005 | WARNING | INI directive ‘mbstring.func_overload’
   is deprecated since PHP 7.2 1009 | WARNING | INI directive ‘mbstring.func_overload’
   is deprecated since PHP 7.2
 * Can you help me resolve these, so that I can update my website to the latest 
   PHP?
    Thank you! Pavel Pavlov

 * AFAIK, only Bitrix is requiring **mbstring.func_overload** set to value greater
   than **0**
 * For WordPress you should always use
    **mbstring.func_overload = 0** which is 
   default value (You can just remove the setting from php.ini)
 * Having this setting set to other value than 0 can lead to various problems with
   plugins and sometimes even WP core, those issues are hard to solve, unless you
   reset mbstring.func_overload to 0
 * In the PHP 8.0 this ridiculous setting has been removed completely. Finally and
   for good.

 * Hi,
 * thanks for your post, and sorry for the trouble.
 * No worries, everything’s compatible here, please see [https://wordpress.org/support/topic/is-tablepress-compatible-with-php-7-and-php-7-1/](https://wordpress.org/support/topic/is-tablepress-compatible-with-php-7-and-php-7-1/)
   
   TablePress only uses this PHP function if it is actually available. You can ignore
   these warnings and safely update your site to a modern version of PHP (I recommend
   PHP 7.4.)
 * Regards,
    Tobias
