Solved Header menu changes to vertical during loading.

Hello,

i have the strangest bug and i cant for the life of me figure out where it comes from. When the website loads in, the menu is part of the header in a horizontal fashion, however about 80% of the time when it loads in the menu starts off correctly displayed, and then during the loading process the menu morphs to a vertical menu, stretching the header downwards.

When this happens the first scroll downwards also gets pulled back once before you can continue scrolling downwards, and if you scroll back up one it hits the top it'll move back down a bit too.

The strange part is that about 20% of the time, on refresh or first load, this doesn't happen and everything loads normally.

I've attached two screencaps, one of the menu when it loads normally, and one when it bugs out.

Kind regards,
Bob

 

Dear problemizer,

Thanks for the response. i have tried your solution and although it did not repair the problem directly, once i combined it with turning off a W3 cache plugin it seems to have worked.

Thank you for your time, if the problem somehow does pop up again i will contact your company, as at that point it seems above my paygrade.

Best regards,
Bob
