All hell breaks loose when trying to insert a link to an image or resource in there

Hi,

I recently tried to insert a link to a resource in there. I had an annoying image in there I wanted to change, and tried it this way.

The plugin then proceeded to mess up the entire site, replacing ALL php generated text on all dashboards with:

Warning: preg_replace() [function.preg-replace]: Unknown modifier '/' in /home/content/27/9460927/html/wp-content/plugins/ultimate-branding/ultimate-branding-files/modules/site-wide-text-change.php on line 377

Please, WPMU as the Wordpress Professionals you claim to be, either handle this exception where a user may enter an URL as the string to be replaced or add the functionality.

I expect praying for any change in free plugins, not in paid ones.

Thanks in advance, and as always I will update this post if I manage to figure it out.
