JFBConnect Model usermap error

That's not an issue we've heard of before, but we'll look into why it may be happening. The message shown is a PHP Notice, which means it's really a message to report to 'us' to fix. It's not a critical error or letting you know that something is drastically wrong though. What I'd recommend is setting the "Error Reporting" setting in the Joomla -> Global Configuration area to "None". That will disable the notification type messages from PHP from being shown and should hide that message.

Again, we'll still look into the cause, but the above is the best temporarily solution to get around that message.

I hope that helps,

The PHP Notices can be fixed using the method I mentioned above, specifically:

What I'd recommend is setting the "Error Reporting" setting in the Joomla -> Global Configuration area to "None". That will disable the notification type messages from PHP from being shown and should hide that message.

It's possible that removing those messages will fix the strange characters as well, since the character set encoding may not be properly being sent to the browser when those errors appear.

As for the Logout button, that's something we'd need to see live to be able to diagnose. From the looks, it seems like there's a template conflict that's trying to set that button to be very large. Once we see the site, we can help provide the CSS that should force the button to the proper size.

Please post, or private message, a link to your site (and preferably some test credentials so we don't have to create an account). We'll gladly test.

Thanks,
Alex
