Support » Plugin: Query Monitor » Conflict with WP All Import

  • I have been using Query Monitor for over a year now and love it. It has saved me so much time debugging issues, so I want to start by saying thank you for what you provide here.

    I recently downloaded a plugin called WP All Import, which imports data into WordPress from a CSV or XML file. I was going through the import steps, and when getting to Step 5 of the process, I just got an all white page with the only text on the page stating: “”WP All Import – Import XML / CSV – Support | Documentation – Warning: your title is blank”.

    I asked the WP All Import team about this, and they said that it’s a plugin conflict issue. So, after deactivating all my plugins, and then turning them back on until I found the conflict, I narrowed the issue down to be a conflict with this Query Monitor plugin. After notifying their support team about this, their response was:

    “We are aware of the Query Monitor plugin causing problems with WP All Import, but I haven’t been able to replicate the issue on our debug site to able to take a look at what is going wrong. The most likely cause is that the Query Monitor plugin is loading some JavaScript which is preventing our code from loading. If that’s the case then the developer of the Query Monitor plugin would need to take a look at the issue and fix it for you.”

    So in order to follow up with them, would it be possible for you to provide me with a response to them? Thanks!

    Query Monitor loads jQuery, but that’s it.

    Can you take a look in your browser console and in your PHP error logs to see if there are any errors appearing?



    FYI – there are a couple threads where this also involves Wordfence

    it is a case of either disable Wordfence, and you can do an WP All Import import


    disable Query Monitor to do the import

    something about having both Wordfence and Query Monitor enabled at the same time breaks WP All Import from loading a php file during the import process



    I concur with @wasanajones, I have both Query Monitor and Wordfence installed, with either one activated WP All Import works, but with both, it fails.

    You can actually test/show this easily by firing up a test WordPress install pre-configured with WP All Import at:

    Then simply install both Query Monitor and Wordfence.

    Run the following tests:
    1) Deactivate Query Monitor & Activate Wordfence = Test all steps of WP All Import = WORKS
    2 ) Activate Query Monitor & Deactivate Wordfence = Test all steps of WP All Import = WORKS
    3) Activate Query Monitor & Activate Wordfence = Test all steps of WP All Import = FAILS
