# Severe PHP 8 compatibility issues

 * My webhoster asked me to switch over all of my domains from PHP 7.x to PHP 8.
   x because they are going to discontinue their support for older/outdated PHP 
   versions soon.
 * Unfortunately, Subscribe2 is not PHP 8 ready yet: After switching a domain to
   PHP 8, the subscriber lists are broken: they are not shown in the plugin’s configuration
   pages and can’t be edited anymore, thus rendering the plugin worthless! Stepping
   down to PHP 7 temporarily solves the problem, but is of course no long-term solution.
 * WordPress, however, does realize the malfunction under PHP 8 and posts the following
   error message:
 * **Uncaught ValueError: Missing format specifier at end of string in …/domain/
   wp-content/plugins/subscribe2/classes/class-s2-list-table.php:430
   Stack trace:
   
   …/
   domain/wp-content/plugins/subscribe2/classes/class-s2-list-table.php(430): sprintf(‘%
   1$s von %2$’, ‘
 * The author(s) of Subscribe2 still seem to be around: Please update and fix Subscribe2
   to make it fit for the future! It is a great but compact tool and all alternative
   plugins I found are way too complex…
 * Thanks,
   Ralph

 * Hi [@zonebattler](https://wordpress.org/support/users/zonebattler/) ,

   website performance and security.
 * We appreciate your patience during this process as we strive to deliver a seamless
   and reliable experience for all our users. Your feedback is invaluable in helping
