Invalid argument supplied


I ran into a crash on my Opigno installation and tried to restore it from backups I had made.

I deleted all the old files system, except for the sites/default structure which contains some php settings files - i.e. shared hosting system/php would not let me delete them. I then extracted the filesystem back-up into the original site, although I did nothing with the sql database which, was already installed / same as before. Everything seems to work OK except for a couple of strange issues that suddenly materialised whilst working on the LMS.

Although I have administrator rights (double checked twice in permissions), it is now denying me access to the Appearance/Manage Display Settings option in the Opigno Administration menu. I have no idea why or how best to correct this. I can see no way to do it through the Opigno permissions interface, so that means I have to use chmod via C-Panel. Whilst I understand the system in unix permissions principle, I have no idea which file or directory to look for or to which settings the corrupted permissions should be reset to.

I then also started getting the following warning messages...

Invalid argument supplied:- Warning: Invalid argument supplied for foreach() in opigno_collaborative_workspaces_form_node_form_alter() (line 46 of /home/liikanjitsu/public_html/mindsets.eu/pedles/opigno_d71/profiles/opigno_lms/modules/opigno/opigno_moxtra_app/modules/opigno_collaborative_workspaces/includes/opigno_collaborative_workspaces.node_form.inc).

Warning: Invalid argument supplied for foreach() in opigno_class_app_views_query_alter() (line 408 of /home/liikanjitsu/public_html/mindsets.eu/pedles/opigno_d71/profiles/opigno_lms/modules/opigno/opigno_class_app/opigno_class_app.module).

I have not signed up for the free trial on the workspaces yet, so that may have something to do with the first error message. However, I have not touched the opigno:class:app module at all. In both cases I did not notice any such error messages in the original instance before I restored from back-up.

Can anyone give me any pointers?
