I also encoutered that error, and fixed it on my install...
(strange enough it came long time after i moved to UTF-8)
somehow the gallery options are not passed on.. dont ask me why...
as a quickfix:
open forum/includes/functions_gallery.php
find this:
Code:
Content visible to verified customers only.
Just
Above (!) add
Code:
Content visible to verified customers only.
That should get you running again..

PS: In my case it came from the fact that i was calling the function from outside gallery...(in a hack) so its normal but in your case the ppg_options should be there...
Are you sure everything went right while updating your database to utf-8? are all text fields utf-8_general_ci? Also I experienced some problem when using mysql vs. mysqli in php
Also I had some post problem when I had saved a php file in UTF-8... (that made the zip compression stall) - so the php files had to stay ansi..
