I updated campground.com yesterday and now the admin login insists that the un and pw don't match... this happens repeatedly. But when I open a new tab and retype (with no index.php on the end) it immediately goes to the dashboard and I'm logged in...anyone else have this problem? Any ideas how to solve? The other problem I'm experiencing using Akeeba back-up it throws the following error:

Warnings
Backup Failed

The backup operation has been halted because an error was detected.
The last error message was:

Invalid AJAX data:

Ideas?



Update to 1.5.20 has broken admin log-in
