Highend Issues

Hello,

I’m having a number of issues with the Highend theme since WP upgraded to PHP 7.4.16

– Revolution Slider no longer works. If I activate it I am locked out of the website.
– Theme Options are no longer responsive. – If I try to open or change anything They just reload to the top of the page.
– Not able to upgrade the theme.
– Visual Composer does not work, I’m not sure it ever has actually.

Please help.

James
