Majesty overrides the CSS that Max Mega Menu outputs. This effectively means the theme hijacks control of the menu from Max Mega Menu.
For this reason, we do not support issues that arise when using Max Mega Menu or Max Mega Menu Pro with Majesty. Please direct any support issues to the theme authors.
If you have bought Max Mega Menu Pro to use with Majesty, and are running into compatibility issues, please get in touch and we will be happy to offer a refund.
