BO all forms stoped working

[B3aT]

Hello

I have a problem with a prestashop installation, all form from backoffice admin stopped working.

Every change I try to make, to accounts, products, filters etc after posting the form all the fields are empty and "required field" errors appears.

I modified the "admin/index.php" file and output the POST data, and is always empty.

if (Validate::isLoadedObject($adminObj))
{
if ($adminObj->checkToken())
{echo 'POST:';print_r($_POST);

First I thought is from the token, and I even repaired a bug http://forge.prestashop.com/browse/PSCFI-2379 , but still doesn't work.

Even the search is affected.

The last modification were at Tabs (moved some tabs), It has any connection with them ?

When I try to modify the Employees general options the " Invalid security token" red error occur.

All users and tabs are affected and I use PrestaShop™ 1.4.0.17

I cannot update momentarily to the last version, I just want to update some products really fast and I cannot, has someone a clue ?

Thanks

Hello,

It might be from your last modification, try to revert to the original files and see if this errors will occur.

I didn't modified any file, just after the error.

I just rearranged some tabs from AdminTabs I think.

Every since 1.4 versions Ive got only but problems, I can`t even modify ANY of my modules, when I press "Config" it sais "module unistalled" and that's it ...


In the admin folder the only time that $_POST has values it's on homepage,
POST:Array ( [tab] => AdminHome [token] => 48a8281a..........
On the rest of the pages Ive got POST:Array ( )

When I try to modify a product sends me on the category page after I hit Save
