Having problems with log in and log out

Neil,
We don't keep admin credentials for sites after we're done debugging, so I don't have those anymore.

As for your issue, looking at your site, you don't look to have the JFBConnect - System plugin enabled. If you do have it enabled, check also if you have the System - Cache plugin enabled, and if so, the cache plugin should be ordered last (after everything else). That's because it caches full pages of your site, and if it does this before the other system plugins fire, it can cause only part of the page to be cached and that won't be shown properly later.

Not sure where the other problems you mention are coming from, especially on this site, as we haven't heard of any similar issues or can reproduce them ourselves. If the above doesn't help, or if it does, but doesn't fix everything, definitely let us know.

Thanks,
Alex
