I have been getting this error message for several weeks now. It is random, most of the time I do not have a problem viewing pictures in the gallery. But every now and then I this message comes up: "Jamie Miles, you do not have permission to access this page. This could be due to one of several reasons: 1. Your user account may not have sufficient privileges to access this page. Are you trying to edit someone else's post, access administrative features or some other privileged system? 2. If you are trying to post, the administrator may have disabled your account, or it may be awaiting activation." It almost always happens when I click on one of the random gallery pictures at the top of the forum index page. Not all the time though. edit: just happened again... took a screen capture of it:
I created a section in the gallery that I only have access to for article and misc site pictures. An incorrect setting in the gallery was displaying the pictures on the forum homepage and since I only have access to this section, the error showed up when you clicked on the image.
