The demo site for SuperConstruction Plus is still running with jQuery 1.12.4. WordPress has updated their jQuery versions to jQuery 3.5.1 and migrate 3.3.2.
With these updates the MeanMenu icon for window size smaller than 1050 pixels no longer appears on three sites I have. Mobile users have no way to access the main menu when this happens.
My fix so far has been to manually install a header with jQuery 1.12.4 and this works for now. It prevents other updates to WordPress from working.
Do you have any suggestions or ideas on how to work with MeanMenu or find an alternative solution for mobile menus? Thanks.
