I have found a couple other places on the forum where people have reported this problem, but no solution that seems appropriate for me, so forgive me if I've missed it- I have looked! I have a site built on Joomla 1.5.7 in legacy mode, and I've tried both 2.0.0b1 and legacy 1.14.3 versions of RSG2, in both instances I'm unable to save the back end configuration of the component.
After a save attempt, the browser reflects this link:
http://mysite.com/administrator/index2.php?option=com_rsgallery2&rsgOption=config&task=showConfig#Any help would be greatly appreciated!
