Problem with manual upgrade I tried to upgrade a website that I have to the latest version 2.6.2930 from an older 2.6.2804 and for an unknown reason the upgrade failed. I couldn't log in the administration area but the front end was working.

Now I tried to roll back to an old backup that I had 20 days ago. So I restored mysql database askitis.gr_160813_184933_v2.6.2804.sql and I uploaded only the folder /craft/app from the older version of craft Craft-2.6.2804

Now when I get to the website administration panel I get the button to finish up the installation like I'm updating the website. Any ideas what's going on? According to everything I read in order to roll back you need the db and files to be of the same version. I check the craft_info and this is the case
Delete your craft/storage/runtime/cache and craft/storage/runtime/compiled_templates folder after doing this manual update.

Otherwise Craft still references the (now renamed) Garnish Javascript, and the UI for the AdminCP is not functional.
