Whoops! Sorry, but you are not allowed to perform the action requested.

Hi,

If a new customer puts something in their cart on my store and then tries to check out, they get the following timeout error message:

Whoops! Sorry, but you are not allowed to perform the action requested.

You are still logged in to your account and may continue shopping. Please choose a destination from a menu.

If they then go ahead and add another item to the shopping cart, then click on checkout it works fine.

This is really baffling!

Any help is appreciated.

 

Broken /includes/classes/shopping_cart.php file. Most common problem is using an addon that contains an old version of the file, instead of the new version.

 

i fixed the problem by replacing the file /includes/classes/shopping_cart.php to the latest version. thank you so much!
