Revolution Slider not working since forcing site-wide SSL

Hi,

So we’re having a few issues with Rev Slider in the back-end of WordPress in terms of:

– can’t update more than one thing at a time without having to save/refresh after each change;
– when in ‘slider settings’ we are unable to select any further settings from the menu down the right hand side;

WordPress, the theme (U-design) and Rev Slider all fully up to date. The only thing that has changed recently is we have implemented an SSL certificate (whole site is now HTTPS) – not sure if that would be causing the issues and no idea how to fix it if it is!

Can anyone help? Thanks in advance.

Thanks.
