Yes, I think - as I grok from code, for alphabets outside US-ASCII PHP must have mbstring support, namely result of

is_callable('mb_substr'))

must be TRUE

sorry mate, does this mean that you can implement this hack for nonascii characters support in some kind of patch, or even about to release a new version of RE?

and also, a simple 123 howto for checking your host regarding this mb_substr would be helpful. can it be found in phpinfo?

sorry mate, does this mean that you can implement this hack

Sorry, but it doesn't mean - I nkow where to see, what to see, probably can debug, but working code can be outside of my (humble) possibilities

There is such an action already under Elgg 1.5 (although it is called "featured").

If you are getting this error, it sounds like you may have a broken group plugin.

Perhaps you could backup mod/groups, delete it and re-install from the Elgg 1.5 release?

Or do you have another groups plugin interfering with the main one?

it's an idea .. I will try it. thank you for propose

EDIT: I tried now with Groups 1.5.1 and with the original one .. both same problem
EDIT²: I tried after disabling every plugin, just groups enabled, .. no changes .. same problem .. with 1.5.1 and original
