We are running 4.5.3 and recently updated to v4.16.2 of the theme. We did have some issues (with our media library and uploads if I recall) with jQuery but have been having no problems by sticking to v1.11.3 using the following bit of code in our functions.php:
We did try and isolate 3rd party plugins to no avail, we are using Govintranet 4.17. I also noticed a post from eleonora that had simliar issues “a little update, the dropdown categories boxes in the search documents page don’t work anymore..”
Another issue also highlighted to our install is now HT Most Active is disappearing on a refresh. If i change the widgets config it will re-appear until the next refresh.
