Up until yesterday at 12 noon my site was working fine. It'd taken a few years to get it how I, and others, liked it. Suddenly I get a message flash up on screeen so fast I couldn't read it "Bonafide" "Error" and "warning" was all I saw. My theme then reverted back to one I used about two years ago and it looks awful -also,I cannot rebuild the page as there is no way to replace the old, ugly header. Worst of all I seem to be able to only activate four themes -NONE of them the one I used before and I can't remember which one it was!!!
Any help or advice welcome.
