Hi Dartho
your suggestion to remove <base href="{vb:raw vboptions.bburl}/" /> from the headinclude didn't work I'm afraid.
there is
this vBulletin bug which has a fix, but I am unsure where to implement it in your code or even if it applies!
Thanks for the header idea, I have since moved it down into some white space where pudgy fingers on a small screen can hit it without zooming.
