XF 1.4 Serious bug! Opening forums scrolls the page to the bottom in Chrome

[Stuart Wright]

Using the latest version of Chrome for Windows (38.0.2125.101 m), when I open categories, the page opens fine.
2 examples:
1) https://www.avforums.com/categories/video-game-forums.517/ (reduce the window height to create a vertical scroll bar)
and 2) https://www.avforums.com/categories/playstation-forums.518/
But if I navigate into a forum, the page opens scrolled to the bottom.
2 examples:
1) https://www.avforums.com/forums/which-tv-should-i-buy.367/
2) https://www.avforums.com/forums/movie-forum.37/
This happens when you open every forum.

Opening all other page types seems to be fine.
This happens when logged in or as a guest.

I'm desperate for help because this is a problem which makes our forums look rubbish for all users on the latest version of Chrome on Windows at least. (It doesn't happen on Chrome for iOS).

[Edit : this happens in the default Xenforo style also, so could this be Javascript rather than css?]

Can anyone please take a look at our forums and help?
Thanks

Does it do it on your sandbox?

If so, try a default style to rule that out.

Then you may need to start disabling add-ons.

Thanks Paul. Went straight for Defer JS and once disabled, the problem goes away.
So some Javascript being moved by Defer JS is causing the page to scroll to the bottom.

I'd be starting with looking at why you have the exelator hijack virus in your page source code!

Nevermind, obviously not the issue. Suggest you still look at your exelator issue though.

I'd be starting with looking at why you have the exelator hijack virus is your page source code!

If you mean

<SCRIPT TYPE="text/javascript" SRC="https://loadeu.exelator.com/load/?p=445&c=1381178&g=051&j=d&ctg=&kw="></script>

that's not a hijack virus.

loadm.exelator.com is well known, and it's the same domain. Made to look like exelate.com analytics. Had my "spidey tingles" going off when you raised the issue.

I'll look in to it, thanks.

I've also had this recently happen with the latest chrome version. IE, Firefox and older versions of Chrome are unaffected.

Disabling the DeferJS addon and the problem goes away.

I've posted in the Defer JS addon thread. I suggest you do the same to let @Jeremy P know the details.
