Just to put a bow on this topic (in case it helps anybody else out), I went to my server host’s support portal and chatted with an online tech. He was able to reset my theme and get me back online quickly. But thanks again Tara for your input. I told the tech what you suggested (about switching themes) and I think that sped the process up.
Thanks for your reply Tara. I went into my cPanel and accessed the PhpMyAdmin dashboard. Using that I changed current_theme to twentyfifteen. But I still cant log-in. Plus the website still loads with the Panel theme instead of twentyfifteen. At this point I’ve moved over to my hosts website to follow their support docs. Worse comes to worse I’ll raise a ticket with them.
Thanks for your help
