[Solved] Fata error: Uncaught TypeError: array_merge()

Hi all,

After attempting to update wpDiscuz to version 7.5.3, we are getting the following error when trying to activate it.

Fatal error: Uncaught TypeError: array_merge(): Argument #2 must be of type array, string given in

WordPress is running PHP 8.0.22.  We cannot activate the plugin due to this error.

Any help is appreciated!
