Still no luck, but I'm trying a few other things. When I look at the JS console in the browser, I see these two files before the cookie.js file:
After cookie.js, there's also:
... and a bunch of others under the theme
I wonder if any of those are causing the issue? We have a bunch of plugins we're using, including 3-4 related to Neatline, and I wonder if there's a conflict?
EDIT: The console also throws this error:
"Uncaught TypeError: jQuery.cookie is not a function
at dispatch (jquery.min.js:3)
at r.handle (jquery.min.js:3)"
That seems to be a good clue, but not sure what to fix =/
Also, is it strange that there are two jquery.min.js files? I found this description of a similar problem, but I don't then know why there would be two min.js files (different versions) called - would this be a plug-in doing something?
Edit2: Found the problem. Double call to jQuery files caused the error. Discovered that previous developer here added an extra line in the themes/seasons/common/header.php file that calls the second file. Once I got rid of that, it works. However now I wonder what else I've broken.... (!)
