My prestashop version is 1.5.6. When i click on menu 1-click upgrade i cannot see the configuration of the module. I see only a white page, totally white. I have tried to disinstall module and reinstall again but the problem stille remain.

Anyone has suggestions?

Hi,

 

can you please allow debug mode, otherwise there¨s nothing much that we can do..

To know exactly what kind of issues and errors you are getting, find the file defines.inc.php which can be found here: /config/defines.inc.php

 

Then open that files and find the line:

define('_PS_MODE_DEV_', false);

 

replace the false with true as follows:

define('_PS_MODE_DEV_', true);

 

Afterwards, reload your page and copy and paste the errors on the page here..

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.
