After having setup several new CP installs lately, based on 1.1.x, I’ve repeatedly ran into issues concerning JS-loading / optimization, esp. with Autoptimize and the likes.
My current “workaround” is to disable Autoptimize, as its author seems to have gone somewhat into feature creep mode anyway, but its just a temporary solution.
So the most recent install included a direct switch from WP 4.9.9 to CP 1.1.1, and the errors were so numerous the client decided to switch back, for now. There were errors about data being served with the wrong mime type in the Admin interface, which I would neglect for, but esp. the jQuery loading issues in the frontend were … NOT SO trivial. This is the second installation, specifically with 1.1.1, that had this issue.
Have there been any changes with eg. the default loading sequence of jQuery and the likes?
