Trouble with modules after upgrading to 1.1.1

I recently updated from 1.0.5 to 1.1.1, and after this the modules-section in admin doesn't show. I only get a blank page whenever I try to view and edit the modules.

I am quite a newbie, so maybe this is a no-brainer, but I don't understand what I have to do to make it show up again.

Make sure your IP-address is in the range of exceptions to see errors in config.inc.php. You can also check data/errors.log

You probably have a conflicting module generating an error.

The errorlog returned this error:""Censored""/includes/classes/order_action.inc.php) [function.require-once]: failed to open stream: No such file or directory in ~/includes/app_header.inc.php (Line 59) /admin/index.php?app=orders&doc=orders
[28-Feb-2014 14:46:18 Europe/Oslo] PHP Fatal error: require_once() [function.require]: Failed opening required '""Censored""/includes/classes/order_action.inc.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in ""Censored""/includes/app_header.inc.php on line 59

Any idea what I can do to fix this?

After you dropped the new files on top, did you run the upgrade script ~/install/upgrade.php? If not, go to http://www.yoursite.com/install/upgrade.php

These are files that are deleted and moved in 1.1 and the upgrade script should have handled these.

Yes, I did run the upgrade script and all seemed fine

So you think there is a bug in the upgrade script? Could there be a permission problem? We have yet not heard anyone else with the same problem.

You can look at the UPGRADE.md doc to see changes between each new version. That gives you the ability to manually solve the problem.

I found out what was wrong.... I had renamed the admin folder on first install, and forgot this on upgrade. Sorry!! my mistake.
