I have been working with this issue for several days and wanted to let the community know of an incompatibility with Fireboard 1.04, Joomla 1.54 and Modalinks 1.05. When using modalinks and selected the "enable on external links" the profile section of the forum is broken. If the external links is set to "no" then modalinks and Fireboard work find. I have attached screen shots of both the modalinks config and the broken profile screen. Hope this helps someone in the future.
