A few weeks ago WordPress version 5.5 was released. I updated our website but in the process broke the dropdown menus. Apparently there are MANY WordPress websites that were broken by the latest release. WordPress released a plugin as a temporary fix to allow time for the theme developers to fix their themes.
We were using a theme by FlexiThemes. They have hundreds of themes that are all apparently broken. The developer has been silent on any fixes coming out. I suspect he has abandoned his theme developement.
So, I have switched to a new theme that doesn’t have the menu problem. Everything appears to be working but if you find something that isn’t please let me know.
