Hi, My server runs on latest ISPconfig version with Apache, Mysql and PHP of course.. I have more than one site on the server, static HTML, Joomla and Prestashop sites. I can't install any addon on Joomla or prestashop. When I try that, I get this error on both cases: On all my sites, I am using Fast-CGI with SuEXEC ticked. Any help ? Kareem.
