Could not load... errors on oc2.0.3.1 rebuild

Hi - I'm rebuilding my OC2.0.3.1 site but when attempting to install some modules I get an error like the below:

Notice: Error: Could not load model /www1/b09/test.angeldancewear.co.uk/web/admin/model/module/errorlogmanager.php! in /www1/b09/test.angeldancewear.co.uk/web/system/modification/system/engine/loader.php on line 24

The files mentioned in the error are both present in the file system, and I can manually open them

What would cause this error, and what might fix it?

Thanks

Have you tried going into extensions/modifications and clicking Refresh

Yes - tried a refresh but wioth no success.

Changing the file permission to 755 seems to have fixed it

Thanks
