Alas, it twas the WP Socializer plug in wrecking havoc.. or not having been configured properly.
I have uploaded the original header.php, one that I have never edited or even opened.
I am getting the same error on other machines, different browsers. Same result.. baffling, would really love not to have to reinstall everything 🙂
Thanks for the reply though.
Forgot this info:
WP 3.81
Theme: Astro, Pirenko.
