Hi, I use CMC plugins on my site and recently upgraded either Joomla or another module and a Javascript error with CMC has now come to light. It seems like the error existed before the upgrade, but it did not prevent any other components (scripts) from loading as it does now, so I never sought to get it fixed.

When I enable the following module, I get a Javascript error:
CMC - Newsletter subscription, Site, Module, 4.1.0

I've now disabled the module on a couple of pages. The error is still present on my site homepage (https://echoactive.com), when I check Chrome Console, I get:
