# [Plugin: Jetpack by WordPress.com] Mobile theme breaks site

 * I didn’t debug but I will a bit later on.
 * The moment I turned on Mobile theme the site broke with a 500 Internal Server
   error which I assume is a fatal error of some sort.
 * I’ll post back here once I find the problem.
    If someone else has a solution 
   please post here too.

 * This sounds like probably the same problem as [http://wordpress.org/support/topic/fatal-error-call-to-undefined-function-jetpack_is_mobile?replies=10#post-3208065](http://wordpress.org/support/topic/fatal-error-call-to-undefined-function-jetpack_is_mobile?replies=10#post-3208065)
   I think we have it fixed for a bugfix release tomorrow, but I can’t personally
   reproduce the bug.

 * I’ve reproduced the bug, and until Jetpack 1.8.1 comes out, you can “fix” the
   problem by enabling the Subscriptions module.
 * If you already had the Subscriptions module enabled, let me know.

 * This bug has been fixed in Jetpack 1.8.1, which is now available at [http://wordpress.org/extend/plugins/jetpack/](http://wordpress.org/extend/plugins/jetpack/)
