 * Hi there,
    I’ve a serious problem on my site: [http://www.drivingexpo2015.com](http://www.drivingexpo2015.com)
 * With NextGen activated I receive the error:
    Fatal error: Unknown: Cannot use
   output buffering in output buffering display handlers in Unknown on line 0
 * If I deactivate the plugin all works fine.
 * If you need any help let me know.
 * THX alot
    Maurizio

 * [@maurixx](https://wordpress.org/support/users/maurixx/) – Have you tried seeing
   if this is a conflict with another active plugin? Perhaps try deactivating all
   other plugins then activating NextGEN Gallery first followed by the plugins that
   were active.
