Javascript error in checkout

[lpks]

Hi,
When I enable OPC in checkout, I get the following error in Chrome Developer Tools when a user clicks the 'create account' button:
Uncaught ReferenceError: op_noshipping is not definedonepage.js?opcversion=2_0_274_021214:224
Onepage.op_runSStabcontent.js?opcversion=2_0_274_021214:241
onRegisterPressedcart.html?Itemid=0:1266 onclick

When a user clicks the login button, it says:
Uncaught ReferenceError: op_com_user is not definedonepage.js?opcversion=2_0_274_021214:5758 Onepage.op_logincart.html?Itemid=0:1290 onclick

hello, are there any other errors, like 404's ?

maybe you need to disable opc's javascript loaded from the cache directory as shown here:

Brilliant Stan - that solved the issue for us.
Thanks so much!

hello, you are welcome. let us know what is the name of the security software that disabled loading of js from the cache directory. right now i know only about the akeeba admin tools. i am going to add a check into opc so it disables this option once the plugin is found.
