I have inherited a 1.4.0.17 Prestashop which I would like to upgrade. I have duplicated the site onto a subdomain and am attempting to install 1 click upgrade. However the modules page show the following error. Fatal error: Class 'Shop' not found in /home/xxxxxx/public_html/modules/avalaratax/backward_compatibility/Context.php on line 254 The problem occurs on both the live and my test subdomain. I tried using the latest version of the avalaratax module, by replacing the folder with the latest download but same error (maybe different line) If I rename the avalaratax folder in and attempt to disable it I get this error. Fatal error: Class 'eBayCountrySpec' not found in /home/xxxxxx/public_html/classes/Module.php(408) : eval()'d code on line 117 Any help would be appreciated.

Did you find a solution to this problem as I am having a similar error but at different line numbers. I have inherited a version 1.4.0.17 shop that I am desperate to upgrade, but cannot install the 1 click installer because of this error!
