Hi, I'm getting this error message -
Fatal error: Call to undefined function jetpack_is_mobile() in /home1/loveyow0/public_html/wp-content/plugins/jetpack/modules/custom-css/custom-css.php on line 17
The only thing I can think would have caused it is when I went to jetpack and clicked to activate custom css. Then when I tried to click to another page, I kept getting that message.
I can't log in to my dashboard or anything as I just keep getting this message. So I thought I might be able to fix the problem in my webhost (I'm with Bluehost)account file manager, and I've found the line the message refers to, I just don't know what I need to do to fix it.
I also can't access my website as a "customer".
Can anybody help? I can't get any access to my website at all. I need to fix this fast!
