What version of Zen Cart are you using (again, being lazy)?
Using
- ZC1.5.5e
- jscript_framework.php version: OPC v1.4.1 (I checked just now with Beyond Compare to confirm this)
- Responsive Sheffield Blue v2.0 template with ZC1.5.5 compatibility code changes applied. This included reverting to the ZC1.5.5e version of jscript_framework.php.

So when I installed the OPC 1.4.1, I used that OPC version of ../includes/templates/MY_TEMPLATE/jscript/jscript_framework.php without merging.

Should I have merged the ZC and OPC versions? I did look at this with Beyond Compare...but to a newbie like me, the changes seemed such that adopting the OPC version seemed the wisest choice.

Thanks
