 * Hello,
 * I noticed today that this mod slowed down the plugin update and install of other
   plugins. I don’t know what else is not working correct but all is working fine
   after disabling this plugin.
 * All other plugins are up to date, also WordPress. This mod is probably not compatible
   with the latest WordPress version?
 * Regards, Vincent

 * On three occurences is depreciated PHP used. That results in heavy processor 
   load en error logs every 30 seconds. That causes this problem with latest WordPress
   and PHP 8.1.
 * The error holds this info and that function is used on three places:
    Got error‘
   PHP message: All-in-One Event Calendar: preg_split(): Passing null to parameter#
   3 ($limit) of type int is deprecated @ /home/sta…. wp-content/plugins/all-in-
