Hi, thanks for the contribution, appreciate the response, thanks. I get a fail to load favicon.ico error, and an invalid CSS property declarations in the warnings. Could it be as simple as not having an .ico? I will try this.
I also removed the 'offending' script which solves the pop up on mobile devices, though on lisacutts.co.uk from an iphone what was the text at the bottom (not footer text) now appears off the bottom of the page in white space. How odd!
Will post any updates soon, thanks for offering some solutions! :-)
