Just noticed another error when enabling capcha:

 

ypeError: Argument 2 passed to WHMCS\Utility\Captcha\Recaptcha::validate() must be an instance of WHMCS\Utility\Captcha\object, instance of class@anonymous given, called in /home/whmcs/www/vendor/whmcs/whmcs-foundation/lib/Utility/Captcha.php on line 0 and defined in /home/whmcs/www/vendor/whmcs/whmcs-foundation/lib/Utility/Captcha/Recaptcha.php:0

 

 

[guy]

it's been fixed.

 

Seems we had corruption in /home/whmcs/www/vendor/whmcs/whmcs-foundation

we took it from a working server and it works now.

@guy How did you upgrade? Using the automatic updater or the patch files?

Hi

 

I started update via web interface, which got stuck after 10 minutes and I stopped it. Which made the whmcs updated. Then when we saw the errors

I applied the two patchs from 13.1 -> 13.2 -> 13.3 and when it did't solve the problem I applied full release on working dir which did'nt help either.

I noticed a diffrence in the file size in whmcs-foundations directory from the problematic server to a working server which was updated only with the two patchs, so I took the directory from there

and put it in the problem server which solved the problems.

this is error due to the developer doesn't add php7.4 support to 8.13.3

you can try to update your php or wait untill this support will be added

Possibly an incompatibility issue with your current php version.

Are you using a php version below 8.2

Hi,

A client of mine experienced this issue.

I opened a ticket and the bug was confirmed.

It was suggested to change the PHP version, which wasn't feasible for us, so we updated to the new patch 8.13.3-release.2 instead, and that resolved the issue.

Quote

There was an issue with the first build of WHMCS 8.13.3 which prevented it from functioning correctly whilst using PHP 7.x.

I would expect that either:

1. Switching to PHP 8.1 or 8.2

OR

2. Swap out your WHMCS files for fresh ones obtained from https://download.whmcs.com

Should you decide to go with the second option, which is a more direct fix, then please make sure you take a full filesystem and database backup before proceeding.

Let us know if you require any further assistance.
