Support » Plugin: Smush Image Compression and Optimization » Does it work with multi-site?

  • Resolved wn nj



    It works with single installation with CDN turned on and under WP 3.8.1.

    However, on my multisite, with CDN turned on, I get a fatal error message:

    Fatal error: Class ‘QM_Backtrace’ not found in
    …/wp-content/plugins/wp-smushit/wp-smushit.php on line 102

    I get the same error whether in the network or in the sub-site.

    Kindly advise.

    Hi @wn nj,

    Hope you’re well today! 🙂

    Yes, the plugin works with Multisite. Have you tried without the CDN to see how it works with that? Not sure if that can simply be disabled for testing but hoping so.

    Also, could we get details on your site? Which CDN for example? Are the images themselves stored locally on your server?

    Looking forward to getting that sorted.


    Hey there.

    We haven’t heard from you in awhile, so I just wanted to check in to make sure all was good.

    This thread was marked resolved, but please, if you still need help then just respond and open it back up. We can then take it from there. 🙂

    Hope you have a fantastic day!
