Thanks for your help anyway, hopefully someone has the answer!! It only seems to be an issue on one wp site, I have 3 and 2 work fine but this last one doesnt and strangely their all set up the same.
I’ve tried deactivating it but it results in an error code and removing the associated instruction in the php file ruins everything!!
UPDATE: it seems to be an issue when updating the sql tables with what was on the localhost.
It’s really strange, everything on the web host is as on the localhost, there are no plugin’s installed anywhere and I can’t find another file with wp_pagebar declared anywhere.
I have very limited knowlege of code and any help you guy have would be awesome. Removing or altering the line removes the issue but it also screws with the header.
