I submitted a bug report, but that says it’s for a fix across future releases. If this isn’t a widespread issue, and is singular to myself, then why would you release a bug-fix for it?
Thank you for your ongoing support with this issue.
Looking back into the support history, it looks as if this has been an ongoing problem for many months for many users, but has never been publicly solved.
On a related note, all lightbox functionality for the galleries has stopped working from the front-end. This started with the release of 4.4.2 three days ago.
