Hello, I just upgraded a website from 1.4 to 1.6. In the years between the two versions, discounting has changed and now I have quite a lot of cart rules which appear to slow down the website. I have noticed that many people has the problem, but I could not really find a solution. I came to realise that in CartRule::getCustomerCartRules some queries are executed in loops, this looks a lot like what could be causing the problem. Has anyone managed to solve this? Yours, Nicolas

Turns out some modules are not (yet) compatible with 1.6.1.0. I was back to square one and ended up trying manual upgrade (/install/upgrade/upgrade.php) which works perfectly.

Thanks for the answer. I have tried upgrading gradually but it failed for some other reasons that I could not investigate. I ended up using the latest version and it seems that everything is working now, some of my modules have been updated recently and are now compatible.

I finally got the upgrade to run using the archive from Prestashop website. FYI MD5 (prestashop_1.6.0.14.zip) = 147d1a1197f96dcf306fcaf91796739b Now I am stuck with another problem, I am missing some tables. The first table missing is ps_shop_url, but there is also ps_shop and I guess some other. Has anyone encountered this ? Many thanks for any help.

Hello, I am trying to upgrade my Prestashop from 1.4 to 1.6.0.14. I can not yet upgrade to 1.6.1 because of a module I use which is not yet compatible. I have dowloaded the archive and unzipped the content in admin/autoupgrade/latest/prestashop/ and set up the 1 click upgrade module to use this folder. When I run the upgrade it fails after backing up the database with an error 500. In the logs I get this: PHP Fatal error: Interface 'Core_Foundation_Database_EntityInterface' not found in /var/www/project/classes/ObjectModel.php on line 28 Has anyone got an idea on how to make this work ?
