I am unable to get into the dashboard at all. The website address is: http://www.socialmediainfusion.net
Here's what happened - I upgraded to the new version of WP - then I got this message: Fatal error: Call to undefined function wp_is_mobile() in /home/content/27/8359227/html/wp-admin/index.php on line 22
Not sure where the problem was I called my hosting company to see if they were experiencing problems and they were not.
I tried renaming the content and plug-in files on that end, and that did not work, so I changed them back to their original names.
I don't know code and need aa much help as you can give me. I made the mistake of not doing a back up, but am willing to lose everything and start again if I need to in order to get the site up again.
A friend said I'd have to delete something and reload WP - how in the world does one do that?
