Did you by any chance use the JA AVIAN template?

That is a highly tweaked version of RSGallery2.
Upgrading that version will remove all tweaks.

Cheers,

the function you have to tweak is in the file gallery.php in the templates\ja_semantic\html folder.  I added a conditional statement so that it does not display unless the user is Admin or SuperAdmin.

around line # 17 or so find the line that reads
<div id="rsg2-tool">

and place this command before it
<?php if($my->usertype == 'Administrator' || $my->usertype == 'Super Administrator' ){?>

then around line #50 or so, find the four lines as follows
         </li>
       </ul>
   </div>
<?php

and add   }  on the line after that to close out the conditional statement

worked for me. I have many other hacks in my code, so I hope I isolated this one properly.
