When upgrading Admintool, I first used online upgrade and it failed with this error :
Fatal error: Call to a member function load() on a non-object in mywebsite.etc./script.admintools.php on line 355
Then I tried to upgrade from the zip archive and I got exactly the same error.
It is not the first time I upgrade Admintools with my host service, I usually had no problems...
Any idea for help ?
