Help, first database errors caused by JFB, now site down after removal

Not sure what could have caused that. We haven't heard of any database errors before that cause the site to not work. Most occur during installation and are due to unwritable directories.

As for your current dilemma, if you run the following queries on your database, it should disable all of the JFBConnect plugins. Hopefully, that will allow you to get into the admin area again.

UPDATE xxx_extensions SET enabled = 0 WHERE element = "jfbcsystem";
UPDATE xxx_extensions SET enabled = 0 WHERE element = "jfbconnectuser";
UPDATE xxx_extensions SET enabled = 0 WHERE element = "jfbconnectauth";

Change the xxx in each statement to your database prefix.

After you're back up, a couple of questions:
Do you know what version you were using before you upgraded?

What wasn't working before today (with the old version)? That will help narrow down the original cause.

Sorry for the trouble, but we'll get you going,

JFBConnect doesn't touch the jos_menu table during installation or uninstallation. There are things that Joomla does behind the scenes, but we're not in control of that. It sounds like that's an issue with Joomla 2.5 beta 2. We'd done some testing with beta 1, but not extensive tests, and we're certainly not recommending that anyone use JFBConnect (on a production site) with Joomla 2.5 yet.

Did the SQL queries I sent help get into the admin area?

Thanks,
Alex

A little more investigation.. it looks like your site was affected with the bug below in Joomla 2.5 b2:
code.joomla.org/gf/project/joomla/tracke...racker_item_id=27702

It's been fixed in the now available RC1 release. I'm not sure what problems may be on your site now with a partial install (or uninstall) of JFBConnect, but upgrading to RC1 may help. I'm hoping you have a backup of your site from before the upgrade as well, as that may be necessary.

Something else you can try to at least diagnose the error is to edit your configuration.php file and change the following values:With those settings, it's possible that a PHP error will show up on the front end to let you know why the page won't load. It's no guarantee that will help though, depending on what extensions you have installed (especially for 'optimization' type stuff).. but hopefully.
