# Error warning: Another Plugin or Theme is using

 * Another Plugin or Theme is using ‘N2WordpressAssetInjector::output_callback’ 
   to handle output buffers.
    This prevents actively outputing the buffer on-the-
   fly and could severely degrade the performance of this (and many other) Plugins.
   Consider disabling caching and compression plugins (at least during the scanning
   process).
 * How to solve this?
    Thank you

 * It’s hard to say where that output buffer handler is being called from or even
   if it is even a problem.
 * First, does the Complete Scan work, does it finish, and how long does it take?
 * If you can run the scan, does it find any Known Threats?
 * If not then you might want to go through and disable each of your plugins one
   ata time, checking to see if that message goes away.
 * Please let me know what you find and if you need more help you can also email
   me directly:
