    Dear sir/madam,

    When scrolling through my website (in progress) the page stutters. Ive turned off my scrolling progress bar and transparency of the menu but that didn’t fix it. I work with elementor pro and that plugin could also be the cause, but since it is the menu bar stuttering I thought it could also have to do with the theme (but of course I am not sure). This is a link where you can see it, but sometimes it is much worse:

    Best regards,

    Any chance you can deactivate your other plugins one by one to see if the issue goes away? Anything that manipulates scrolling would be my first bet.


    Hi Tom,

    Thanks for the suggestion. When I deactivate GP pro while leaving everything else activated the problem disappears. Any idea what I would have to do to next?

    Best regards,

    That makes sense as the sticky nav is a part of GP Premium.

    You’ll want to deactivate your other plugins to see what’s causing the sticky nav to glitch.


    I deactivated all my plugins except for GP premium and the issue persists, if I deactivate GP premium and none of my other plugins there is no issue. I narrowed it down to the Menu plus part of GP. When I deactivate that everything works well. My menu works fine without the menu plus part but the only thing is then the logo doesn’t appear in my menu, which I want to have of course…

    The sticky menu is a part of Menu Plus.

    Haven’t had any other reports of this, so we need to find what’s unique about your site.

    Do you have a fresh install on your server which you can add a sticky menu to? This will allow us to see if the issue can be reproduced in more than one environment.


    Hi Tom,

    When I turned off the sticky nav in GP everything worked well, because I realised that for other reasons I made the navigation sticky with css in the past (which I forgot about) so now it was “double” sticky which caused the issue. So everything is settled now.
