Hi, I have exactly the same problem. I am using the presta shop version 1.5.6.1 and 1Click Upgrade 1.3.14. After clicking on Configure of Autoupgrade I get blank page. Followed your guidance, now I can see this error message: Fatal error: Call to undefined method AdminSelfUpgrade::addCSS() in /home/html/maruhandmade.sk/public_html/modules/giveit/giveit.php on line 955 Actually I wanted to upgrade the shop as I had problems with upload of product images - when I tried to upload an image, I got error "undefined". Many thanks for your help. L.
