Ok i've updated the permissions on the files in the cache directory and cleared the cache. The Who's Online island has now changed.

Thanks Rick.

What I don't understand is Gizmo's comment:

"And theres a simple way to tell, look at the Who's Online page, a bot will have a "user agent" string that tells you where it's from, and it'll show in the "guests" or "bots" section (it'll show in the bots section if you tell your ubb which UA's are bots)"

Where's the Who's Online page?

Much thanks everyone.

I just visited your site and watched a while and the island is updating. Maybe you followed Ricks suggestion?

But the details link in the island is not showing anything.?ubb=online.
Not sure what to check. I never used version 7.0.
Maybe a permission setting for guests to view.

We must have been typing at the same time.
On my version the whos online setting is in the control panel>general>>expand whos online

Yes... I followed Ricks suggestion.

I don't see the Who's Online setting in the control panel on my version.

Looks like that feature was added in version 7.1.

Read the change log HERE

Ok actually i've noticed calendar information isn't being displayed either and the shout box isn't working. Might this be related to permission errors???

Well All the islands are built the the same cache directory as the whos on line island.
You could try going over Rick's suggestion again and check the individual island scripts for each feature to see if it is set the same as the whos online script which is working now.

I tried to register to see but you moderate registrations.
I can't tell if guests are not allowed to view those features or what.

Thanks Ruben.
