The mb_substr is a function that is a part of PHP by default. It sounds like your hosting company disabled it, which is uncommon, but apparently happens. You can work around this by editing that file, finding the line at 333 that should look like:And changing it to:If you're site uses non-Latin characters (accents, greek letters, etc), the fix above will cause other issues as well. We'd recommend contacting your hosting company to have them enable the mb_substr function as the best fix.

Hope that helps,

Rish,
I'm unsure why the menus would be gone. That sounds like a Joomla issue either from the un-installation or the installation. Not sure how to fix it.. my best suggestion, strangely, would be to uninstall and re-install again and hope that Joomla can clear itself up. The install packages for extensions don't create the menus directly, and rely on Joomla to do that, so it's somewhat out of our hands...

When you uninstall, JFBConnect doesn't remove your configuration settings, so you won't need to start over from scratch.

Finally, for the social networking buttons, we're always working on improvements to them. There are big limitations to what you can do to the look and feel of the Facebook (and other) buttons, but there are some 'mega' sites that have the abilities to get around these limitations. It's not always possible for an extension that's meant to be used on thousands of sites though. We do appreciate the feedback though, and things like the box-count and button-count look of the buttons should all lined up properly as-is. If you're seeing something different, let us know.

Thanks,
Alex
