Hi Marcus, thank you for your response.
Additionally to the issues mentioned before:
a. When I create a new location logged in as admin, the location doesn't show up under "My Locations" but under "All Locations". This works fine for subscribers though.
b. When I upload an image to a location it goes through the process but it won't upload the image unless I try a few times. I wonder if there is a conflict with the EM settings under "Images size". Are these image setting preventing images that are bigger from uploading, or is EM converting automatically images to these parameters? if the last is the case then I guess we need to notify our subscribers about these settings.
c. After a location image is uploaded the image shows up only on the location page but not on the events page when the location is selected. Is this the way it should work?
d. The theme I'm using with BuddyPress 1.2.9 is "Custom Community 1.8". I tried other themes but I have the same problems. Because I can upload images on a location page (with the limitations mentioned above) I don't think the problem with uploading images on the events page is a permission issue. I wonder if the issue is with WP 3.2.2 because I read that the last WP compatible version with EM is WP 3.2.1.
Finally, would the EM Pro version solve all these issues?
