SyntaxError: Invalid regular expression — stack overflow

Hi Frank,
I’ve got an issue I’ve not been able to solve. Odd thing is, it was not occurring previously. I was getting a JQuery issue, so I added JQuery.js back into the JS Exclusions, along with a few others. Full exclusions are:

But somewhere along the way, I started getting these errors:

Uncaught SyntaxError: Invalid regular expression: /(^|\.)cfs1(\.|$)/: Stack overflow

    ... (etc.)

I’ve tried clearing Cache, and Autoptimize, but error continues. Looking in the Autoptimize JS file that’s referred to, I was unable to retermine what original JS file is causing the issue, for exclusion.

Any help would be greatly appreciated.

Thanks,

Jonathan
