Hi, For one of the sites using Joomla in ISPConfig I changed PHP from default PHP to PHP 7.1 Here are the settings: PHP: Fast-CGI PHP Version 7.1.0 Apache/2.4.10 (Debian) WebServer to PHP Interface cgi-fcgi Joomla! Version Joomla! 3.7.2 Stable [ Amani ] 22-May-2017 09:46 GMT I get this error: Error displaying the error page: The memcache Cache Storage is not supported on this platform.: The memcache Cache Storage is not supported on this platform. Only answers I found was to make /administrator/cache folder writable - did not work. Do you think this is related to joomla, php or ispconfig?
