Flaunt Posted November 22, 2010 Share Posted November 22, 2010 Hi,I recently upgraded a store to the latest version of Prestashop. For the most part, everything seems to be working fine. However, I have a problem using any new/current modules I install.When I install a module, I get a message saying everything installed successfully. But, when I go to 'configure' the modules, I get an error message saying:Fatal error: Call to undefined method Module::isinstalled() in /public_html/website-name/admin1/tabs/AdminModules.php on line 125This also happens if I try to configure ALL of the standard modules already installed (Paypal, products etc etc.). I'm sure it all worked fine initially but not anymore.Any ideas what's happening? Link to comment Share on other sites More sharing options...

Flaunt Posted November 22, 2010 Author Share Posted November 22, 2010 Thanks, Phil. I checked permissions and everything seems to be in order. Still no joy. I've copied in an older version of the file (from an older version of PS) for now which is allowing it to work for me. However, I'd prefer to use the proper, current version so I'm still after a more permanent solution! Many thanks Link to comment Share on other sites More sharing options...
