I bought this plugin a year ago and couldnt get it to work. I just bought it again because it the new version and from the start I cant access the settings screen (its just stuck and spinning).  I am really frustrated as I've paid twice and still nothing.  I've disabled all the other plugins and have checked the system requirements.  I used the upload plugin tool in Wp to add and activate, but I tried via FTP and same thing happens.

When I check the console as its trying to open anything (setting, add table etc.) it shows this:

Uncaught TypeError: jQuery(...).animateFadeOut is not a function
    at common.js?ver=4.9.1:234
    at dispatch (load-scripts.php?c=0&load[]=jquery-core,jquery-migrate,utils,moxiejs,plupload&ver=4.9.1:3)
    at r.handle (load-scripts.php?c=0&load[]=jquery-core,jquery-migrate,utils,moxiejs,plupload&ver=4.9.1:3)

r.handle @ load-scripts.php?c=0&load[]=jquery-core,jquery-migrate,utils,moxiejs,plupload&ver=4.9.1:3

Which is referencing this function in your plugin:

/**
 * Hide preloader on window load
 */
jQuery(window).load(function(){
    jQuery('.wdt-preload-layer').animateFadeOut();
});

The site has already been customized for that theme, so that stinks.

Do you have a theme you recommend that wont interfere?

Thanks

That did the trick, thanks! Going to make this reply public so other people can see if they have the same trouble with the settings pages not loading.  Is this issue specific to using any child theme?  Or just the one I was using?

** If you have the same issue: There was a conflict with the theme I was using in Wordpress, try another and make sure to clear browser cache and reload.

Thanks Milan, much appreciated.
