[Resolved] fatal error on iphone (Jetpack mobile is off)

[Ashley Gainer]

Hey, Tom —

I’m getting a fatal error on my site when using an iphone. Jetpack mobile is off and I’m not sure where else to look. Here’s what the error message says:

Fatal error: Call to undefined function generate_main_class() in /home/ashleygainer/public_html/wp-content/plugins/gp-premium/addons/generate-sections/functions/templates/generate-sections-page-template/php on line 18

That’s all Greek to me, but I assume it’s self-explanatory to someone who knows a thing or two…

thanks for any help!

Hi there,

This typically means two things:

1. GeneratePress isn’t activated (or Jetpack Mobile Theme is activated).
2. You’re using an old version of GP Premium

In the latest GP Premium, there’s a safeguard against this error if GP isn’t active for whatever you reason.

Thanks, Tom. Turns out I can’t distinguish “on” from “off” in Jetpack, ergh. I turned it off for realz this time and of course everything’s resolved. Thanks!

Great! Glad I could help 🙂
