Got the error finally! It had nothing to do with the mmenu.js file at all.
While customising the app, I added a function to application/libraries/globals.php in the curatescape theme folder called, you guessed it, get_random_featured_collections (note the s). But when upgrading, globals.php get rewritten during the upgrade process!!!
So don’t mess with anything outside of custom.php. Lesson learned. I also should have read the documentation rather than just hacking away as I usually do. Ugh. I’m sure I added some script somewhere else.
Ah well, at least the homepage is working now!
Thanks so much for your help!
