Once you remove that, the comment box and Like box will grow to the correct size.. at least, from my testing they did. That CSS is embedded on your page (look at the HTML). You'll need to find out what's inserting that and remove it.
Glad to hear we could help you narrow things down and get you going, even if your subscription expired more than 6 months ago
We hope you'll plan to move to Joomla 2.5 or 3.x in the future and upgrade to our latest JFBConnect release as well. There's a lot of great features we've implemented since the version you're using, and a lot more planned over the next few months. Either way, best of luck to you and your site.
I left a rating and review for JFBConnect at Joomla Extension Directory.
But we will not upgrade to J2.5 or J3. Our system is working fine.
It is to complex to upgrade. Many modules and components are not available for J2.5 / 3 and stuff like that.
-> Never change a running system....
Completely understand the hesitation in upgrading. It can definitely be a pain. We did it about a year ago. It certainly wasn't fun, but was necessary (for us). Joomla 1.5 is a solid system.. but there are no more security releases being planned for it, so please stay vigilant.
