Has anyone experienced Menus reordering themselves in Joomla 2.5 ? I have had that happen several times and it seems unlikely it's a hack.
I believe this was a bug when migrating from Joomla 1.5 to 2.5. Whether this is the case for you or not, try the following:
- Login to PhpMyAdmin
- Select the database that is associated with your Joomla site
- Click on the SQL tab
Copy the following database query (change xxx to your own database prefix)
UPDATE XXX_menu SET ordering = 0
This should reset the ordering for you.
Note: Once done, make sure you have the latest version of the Joomla 2.5 series (2.5.28)
Hope this helps
