Trying to add my license info.... get the following error

An error has occurred.

0 call_user_func_array(): Argument #1 ($callback) must be a valid callback, class Joomla\CMS\Cache\Cache does not have a method "cleanCache"

Hi Rashida ,

I am also facing the same issue I am using the Joomla 3 right now and the PHP version 8.0.30.

Can you please guide us on how to resolve this error.

Thanks and Regards.

Hi Darren,

Sorry to hear that.

The error seems related to Joomla and PHP version actually.

However, kindly post a new question with the necessary information, as we need to check it deeply.

Best Regards
