 * Hi,
 * I noticed in my error report there is a constant php error happening in my log,
   it only start happening around the time I installed matomo plugin, so I deactivated
   matomo and the error has stopped 4k instances in one week.
 * Warning: Module “igbinary” is already loaded in Unknown on line 0

 * Hi [@smarti9](https://wordpress.org/support/users/smarti9/), can you try activating
   the “Enable archiving via HTTP requests” setting in `Matomo Analytics > Settings
   > Advanced` and check if the warning still occurs?

 * Hi,
 * I tried that seemed to work, then I tried entering site through url mydomain.
   com and it popped the error again, so I added to ht.access file, because I am
   getting Warning: Undefined array key “host” in .wp-includes/canonical.php as 
   well.
 * Will monitor have at least stopped it happening through non www means, just seems
   to be when matomo is active though.
 * Thanks for all your help much appreciated.

 * Hi,
 * I thought I isolated when it was happening but I was off the mark, have enabled
   archieving via http but its still happening, when I disable matomo it stops. 
   PHP Version 8.2.x

 * Hi, Matomo does not use or reference igbinary at all. The only code I can find
   that checks for the igbinary extension is unused code in dependencies (doctrine
   cache and symfony). Can you find if the error is occurring during a cron task
   or from a web request? And if the latter what HTTP request is causing the error?

 * Marking this as resolved due to a lack of response. If the problem is still occurring
   and you would still like help with it, feel free to reply or create a new issue.
