You haven't identified the version of Zen Cart that you're running or which plugins you've installed, including shipping/payment methods (see the Posting Tips). If you give us a little more information, we'll be better able to help.

Common causes of that error are mismatched files for different ZC versions, particularly with templates built for v1.5.4 being used on v1.5.5 and not fully upgraded.

So in addition to your ZC version and all your plugins, please also list what template you're using and everything you've changed related to javascript files.

A URL would be the most helpful.

I have found the problem,i am using a westminster_new template,there is a jscript_framework.php in jscript folder,after i delete,the problem won't be there,i am wondering what's going on with this file.

I have found the problem,i am using a westminster_new template,there is a jscript_framework.php in jscript folder

Yes, that's your problem.
If you want to use that template on v1.5.5 you will need the v1.5.5 version of the jscript_framework.php file.

Yes, that's your problem.

Due to PayPal “deleting the comma issue”, I had to upgrade from PayPal Standard to PayPal Express. After the upgrade, I received the (35) handshake failure error, which required an upgrade of Zen cart to fix.
I upgraded Zen cart from v1.5.1 to v1.5.5d and this caused “An unknown response null: :text/html; charset=utf-8: :Bad Request was received while processing an ajax call. The action you requested could not be completed” error.
Following your advice, I changed /includes/templates/MY_TEMPLATE/jscript/jscript_framework.php file by copying the one from /includes/template_default/jscript/jscript_framework.php in v155, it worked perfectly and I no longer get the pop up, Thank You.
Is that the only error that you know of from upgrading?
I am using Winchester responsive template and I still need to install Ceon Advanced Shipper 5.0.2 and Ceon URI Map 4.5.1

Check your logs folder for any additional errors generated and actually, the error was generated "by upgrading", but by not maintaining the involved software compatible with the current in use version of ZC. There are likely/possibly other actions necessary to further make the responsive template compatible, but that is an issue to address/discover within the thread for the particular software.

Thank you.
After checking logs there was an error; PHP Warning: constant(): Couldn't find constant includes/functions/admin_access.php on line 38
time for some research.

That should have been fixed in 1.5.3. Might want to check the files and make sure you've got the current version AND take a look at this thread.
