Server issue Base and Exponent Overflow error

[motowebmaster]

Affected version

2.2.16

Started from this discussion, after a PHP 8.2 upgrade was distributed recently:

XF 2.2 Post in thread 'base and exponent overflow'

Nov 29, 2024

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:

return \gmp_pow($base, $exponent);

to:

return $base ** $exponent;

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

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

Same in all three of my own forums runing with Xenforo 2.2.16 and since update PHP 8.2.25 to PHP 8.2.26.

Same in ours, but the temp fix posted by @Moshe1010 seems to work and has stopped the double-posting and Base and Exponent Overflow errors in the XF log.

Hi,

GMP is used for PUSH notifications, in case it is possible to temporarily disable them.
This causes errors and duplicate posts.

PHP 8.2.27 with GMP fix is in preparation, should be released soon

The same problem is present with PHP 8.3.14 and 8.4.1
They should also release PHP 8.3.15 and 8.4.2 soon.

It hasn't been rolled out within cPanel as yet, I've just run an update to see.

Regarding cpanel I advised to release PHP as soon as it was available because they usually take 2 to 7 days via easy apache

Still on 8.2.26 with cPanel

@webbouk

With cPanel It seems like it's a long thing for the release of new versions of PHP

[ciao70]

Has anyone updated to PHP 8.2.27 to see if this fixes the problem?

 

[webbouk]

Not yet, cPanel still hasn't rolled out 8.2.27

Same here - Plesk Panel (up to 18.0.66) uses up to day the olded 8.2.26 and 8.3.14 PHP versions too.

... and I really don't feel like doing it manually again. Damn. (update PHP bevore Plesk releases a newer version with needed new PHP versions)

But mostly Plesk brings out the new PHP versions at the end o month. So we will wait.

cPanel still on 8.2.26

I issued a ticket with Plesk late last week, they pushed 8.2.27 to me yesterday. Switched over to it last night, restarted the webserver, no Xenforo errors
