I have a frustrating problem. In the page source, the first line is blank, which causes issues in some browsers.
These are the steps I've taken to try to fix the problem:
- Gone back to twentythirteen theme
- renamed plugins folder to oldplugins. Checked in admin and they are all deactivated
- Made sure there is nothing outside of the php in index.php, header.php
- cleared out htdoc htaccess
I'm at a loss!
