problems after upgrading from 1.6.0.9 to 1.6.1.5

[webster]

 Hello. I've just upgrade to newest PS version. After that on the left top side spinner is loading something. And dropdown menu (modules, settings, etc) doesnt work.  What should I do? Also does not work performance settings. If I set it rolles back.

Hello. Turn off cache, clear all cache.

Delete file config/class.index.php

Delete cache of your browser.

Manuly replace all files in folders classes, controllers, admin.... by files from archive prestashop 1.6.1.5

then delete file config/class.index.php and clear browser's cache

okey, that solved my problem. But now is another. 

 

when you enter url example.com/en it shows server error 500. But wehen you enter content  page, e.g. /en/prices-drop, /en/my account, etc it works. only error on homepage. how to fix it?

 

P.S I regenerate .htaccess file, but it's no use.

Cleared cache, etc. nothing did.

edit file config/defines.inc.php

turn on dev mode:

define('_PS_MODE_DEV_', true);

 

After that refresh homepage and see the error.

Also write a link to your site.
