I just moved my WordPress install to a new server and it is working however my plugins are not able to change the filesystem.
I tried to uninstall a plugin, it said it could not remove the folder. So I deleted the folder from FTP. Then I tried to install that plugin.
Now I got the error a directory could not be created.
I tried a random other plugin and got the same error.
I checked with Filezilla and all the folders seem to be 777. On my previous host it was 755. So the issue cant be here.
