Thanks Ismayil for your answer.
I don't know, I have not error_log file. It is the CPU of the database that is in over quota. And after the database is down.

Explore the feasibility of upgrading to 1.12, which should be straightforward and yield some performance gains. There are a lot more in 2.3, but that will be harder depending on your plugins.

Ok Steve. Thanks. I will try to upgrade.

Wrap your code in elgg_set_ignore_access

Thanks veryrthing is working now.

In case you don't know, the invisible group can't be loaded for a user who can't see it, so it was passing false into your function. That function turns off the access limitations so the code can see every (enabled) entity, annotation, etc.
