Hi Wayne,
I am sorry for the delayed reply.
I have inspected your site and I believe mod_easyblogcategories is causing this issue. I have temporarily disabled it and now your site is working correctly.
On my inspection, your site is displaying error: require_once(): Failed opening required '...\components\com_easyblog\helpers\helper.php' . Can you check for me this file permission? Can you provide us with FTP access so that we can further debug this issue on your site.
Please advise.
