I have a ModuleLoadException Error the error below appears in the Site Log (in Admin).

I am not aware of anything which has changed, I just logged in one day as the Admin user and most of the content was blank - many modules missing from most of the pages.

I can log in as normal user and as host and everything is ok - all site and all modules appear as normal (as host and normal user).

It's just as Admin user - my content is blank!

here is my error log:

Can anyone decipher what the above means?

Is it perhaps related UserSettings (as noted in Method or ModuleControlSource:)?

When i type in the Raw URL address (above) - it displays the user settings box displayed in our Knowledge Base / or Forum Module.

Perhaps a user has made an erroneous selection and created a bug? but i'm not sure why everything should be blank in the admin account?
When I give a normal user admin permissions - their admin login is ok - it's just the default Admin user account which is corrupt.

Any ideas?
thanks, mark.

I have had a similar experience, although no error code appeared.

One user which has admin rights suddenly reported of content which was dissapearing when he logged in. It was visible as both host and non-registered user. We had to create a new admin user for him.

Is this a known bug of some kind?

Mark,

when it is the Forum 4.4.3 then have a look to this following thread and perform the scripts if you have it not allready done.  It is the first pinned thread about some List errors.
