Recently I moved my test-site to another host and another domain name. After this move I got a black screen in Codemanager. I uninstalled it, reinstalled it and it worked again. 

But since this I am getting a lot of errors when refreshing in Extensions-modifications and the same errors occur when I try to uninstall codemanager again through Extensions-Modules.

Here are the errors:

I checked the permissions on the folders and they are set to 755. Changing to 777 did not solve the problem. I asked my hosting company but they are not able to help me.

Does anyone have a solution for me?

EDIT:

It turned out that when my site was moved from my old host to the new host, the old hosting ftp created .listing files with a 644 permission. This (hidden) files where causing the errors and manually removing them solved my problem.
