- Bonus plugins are not updated. Bonus plugins have no automatic updates so you may need to remove them and download latest version from Rehub – plugins
- You don’t have updated cache. If you use any cache plugin – update cache in it. Even if you don’t use them, cache can be enabled in browser. How to clean cache
Please, make sure that you updated BROWSER cache. If you don’t understand how to do this, google something like “clean browser cache in Chrome”. Without cleaning browser cache, theme option will not work.
For wordpress 5.5 – you must use theme with 11.6 version or newer, Rehub framework plugin 5.9 or newer, RH Import PRO plugin 1.6.7 or newer
