Hey @Sakin, thanks for your response. The only thing I changed in the theme was to add in AdSense and Google Analytics codes. I also did mess around with the header.php to try and fix this issue, but when nothing worked, I recopied the default code from the source document online. Depending on the page I visit, the header links to a different URL.
I also tried uninstalling the theme and reinstalling it, but when I did that all the menus and everything I have added stayed the same, so I don’t think I actually reset anything. Do you have any troubleshooting advice? Could you think of the page in theme editor that might be screwed up? Thanks again for your help!
