I've tried to update to the last Admin Tool version for Joomla 2.5.23 by using the joomla update extension manager capacity.
Then the result was weird because my menus were not in right order.
So, with AdminTool I fixed the permissions, fix the SQL table and emptied temporary files.
And with Joomla I purged caches.
But as I"ve logged out from Joomla administrator page, I'm not able to logon again; each time I try to do so I'm redirected to the homepage.
Unfortunately I do not have any recent backup of that site.
How could I fix it ?
