In tiki-assignpermission.php, if you create a blank level and then, you have blank levels for some permissions, you will get an error like:
The XML page cannot be displayed Cannot view XML input using XSL style sheet. Please correct the error and then click the Refresh button, or try again later. -------------------------------------------------------------------------------- Only one top level element is allowed in an XML document. Error processing resource 'tiki-assignper... <b>Notice</b>: Undefined index: tiki_p_take_quiz in <b>tiki-...
And you can't via the interface re-assign the level to that permission. You need to clean the mess in phpmyadmin
If you have phpmyadmin, to reset permissions to original state:
2- find "Table structure for table users_permissions"
and copy/paste that section (just that section) in sql commands
lines 4001 to 4191

Maybe 1.10 is affected as well...
