Joomla! version: 2.5.14
PHP version: 5.3.19
MySQL version: 5.1.70-cll
Host: hostingmatters
Admin Tools version: 2.5.8
Description of my issue:
When trying to change a password, I get:
Save failed with the following error: You cannot remove your own Super Admin permissions.
I noted that Nicholas had posted on this topic (e.g., #16898 – User Password) and changed the root asset record as recommended, but got Access Denied and so changed it back.
I have run Repair & Optimize from AT Pro, also Cleaned Temp, also Fixed database from Extension Manager / database (no problems).
I am also getting:
Warning: mysqli_fetch_row() expects parameter 1 to be mysqli_result, boolean given in .../libraries/joomla/database/database/mysqli.php on line 469 (also 512), which seems to be associated with Admin Tools, at least some postings have said so.
Suggestions!
Thanks!
