I’m having the same issue, the solution proposed in this thread didn’t work and the update didn’t fix it either
Description of the bug:
1) The first time I hover after loading the page, the tooltip appears with text “Loading glossary term” for an instant. Then, the text disappears and the tooltip remains, empty.
2) The second time I hover, the tooltip appears empty.
This plugin was so promising, what a pity!! ??
