Herman, I just upgraded to WordPress 6.4. I just realized that you’re plug-in is not compatible was 6.4. I’m having trouble getting my sticky menu to work I’ve done everything you wanted me to do, like using a external CSS plug-in for my code. Please let me know when you’re plug-in is compatible.
Anyway, I would like to let you know that this plugin has no compatibility issue with WordPress 6.4. Also, the way to make a Sticky Header as explained in the doc I shared previously; it’s still working. Refer to this video, please.
Well, feel free to start a new thread if you have anything else related to this plugin, we can help you with.
