Hi guys
I'm trying to future proof our site however when switching from PHP 7.4 to 8.0 the Activity Feed sidebar goes missing and we get the following error. When refreshing the site for the first time the screen is blank until you refresh a second time.
[Mon Aug 29 09:39:56.268887 2022] [proxy_fcgi:error] [pid 9738:tid 139736895190784] [client 124.148.96.34:53201] AH01071: Got error 'PHP message: PHP Fatal error: Declaration of IPS\\Theme\\Cache\\hook395::filters() must be compatible with IPS\\Theme\\Cache\\class_core_front_search::filters($baseUrl, $count, $id, $action, $elements, $hiddenValues, $actionButtons, $uploadField, $class = '', $attributes = [], $sidebar = null, $form = null, $errorTabs = null) in /var/www/clients/client260/web359/web/system/Theme/Theme.php(951) : eval()'d code on line 173', referer: https://www.aussiearcade.com/
I've tried disabling all plugins, cleared the cache and no errors show up under Support. We do use 2 custom theme's but both are up to date and the same thing happens on the standard skin.
Any help would be appreciated.
