The error message in your screencast video is an UberMenu Pro error message, it’s not a theme error. You’d need to ask the plugin author about it, it’s not something we can help you with. I don’t know what might cause that error to happen, but I can tell you that I cannot replicate that problem on my Moxie sandbox site. So if you need help with that error, please ask the UberMenu Pro plugin author for support.
But before you do that, try reinstalling the theme. This is the exact procedure to follow…
- Deactivate all plugins except the two recommended by the theme (Slider Revolution and WPBakery Page Builder).
- Note that if you don’t deactivate all additional plugins, all at the same time, the following procedure will be pointless.
- Now download the latest version of the Moxie theme from ThemeForest (the “Installable WordPress file only” option).
- Unzip the file you downloaded from ThemeForest to create a ‘parallelus-moxie’ folder on your computer.
- Use FTP to delete the ‘parallelus-moxie’ theme folder on your server.
- Use FTP to upload the new ‘parallelus-moxie’ theme folder from your computer to your server.
- Once Moxie is reinstalled and activated, in your admin sidebar select Appearance > UberMenu to access the UberMenu Lite control panel.
- If you want rid of the existing menu, simply go to Appearance > Menus and delete it. Then build a new menu.
Please don’t reinstall the theme any other way, please follow the instructions above exactly. If you do not follow these instructions exactly then you may lose your theme settings, i.e. they could all revert to the default settings.
It is important that you deactivate all addition plugins so that we can be sure that none of the additional plugins you have installed is causing the problem.
It is important that you download the theme again from ThemeForest because it has been known for zip files to become corrupted in transmission.
It is also important that you first delete the existing ‘parallelus-moxie’ theme folder on your server before you upload the new one. If you don’t do this you could end up with a theme folder with missing files and a mixture of templates from older and newer versions of the theme, and that can cause problems.
So it is very important that you first delete the existing ‘parallelus-vellum’ theme folder on your server before you upload the new one.
Do not have multiple Moxie theme folders in ‘wp-content/themes’, that alone can cause unpredictable problems. If you feel the need to store old versions of the theme, either download them to your computer and store them there, or move them to another location on your server. When I need to do this I create a ‘backups’ folder in ‘wp-content’.
After reinstalling, remember to refresh your browser’s caches so that it’s not using cached versions of the theme’s CSS and JavaScript files…
