HI,

as of today I get a lot of errors:

What could that cause?

Thanks!

Totally understand. I noticed this error was also causing double posts due to refreshing and posting after receiving the math error so went ahead and upgraded to the stable version of XF. No issues.

I did two things to solve this issue:
1. I disabled all caches via config.php including CSS cache and redis cache (also the regular XF based cache or any other caches your have under config.php)

2. I've edited the Math.PHP file under src -> vendor -> web-token->jwt-util-ecc
backup what you have now and replace line 53
from:
Code: 
return \gmp_pow($base, $exponent);

to:
Code: 
return $base ** $exponent;

clear cloudflare cache as well after all of that and see if it helped...

2.2.16 is the last stable and as PHP 8.2 compatible market in the XF 2.2 series. But since certain days, it isnt any more for now.

It would be interesting to see an official response. Submitted a support ticket.

Same Problem here. XF 2.2.15 and since over a year PHP 8.2. Now suddenly double postings and the mentioned errors.

I changed to PHP 8.3, but still get the error
