after adding an event (as group leader), the invite guest function is not working, the buttons in the page source are on display: none.

moreover I cannot see my groups in the group dropdown.

as 171, dnn495, default dnn skin

This sounds like you using a host account or the account being used is not a member of the community role. Is that possible?

no it is the group admin, and he is in the community role. In my case the community role is not reg users.

I can't find any problems with this feature. Does this happen from the main group active tab? Are there any javascript errors on the page?

it happens in ie7, no js errors. yes in the main group active tab

Any exceptions in your site logs Peter?

no I am pretty sure it is an ajax/js/css issue in IE7. Some screens in ie7 simply don't work well (even when they look fine in IE8 in compatibility mode). They just have to test it in IE7.

Hmm, not had any issues personally. Have you tried doing a fiddler trace or perhaps looking with firebug?

did you test in IE7?

Every release is tested with IE7,IE8,FireFox,Safari, Chrome and Opera. Please post some screen captures of what you are seeing or create a support ticket.

Thanks,
Will

Peter - yes - tested same versions as Will / ActiveModule staff.
