QM Drop-in issue with WP All Import plugin

[shivapoudel]

Let's replicate the bug.

1. Create a sandbox environment for testing over here: https://www.wpallimport.com/debug/
2. Go to the "All Import > New Import" page.
3. Upload the "sample.csv" file and select Create new "WooCommerce Products".
4. Continue to step 2 and again to step 3.
5. Just drag the "product_name" as a title for testing.
6. Continue to step 4 and the issue arises within "admin.php?page=pmxi-admin-import&action=options"
7. Hurray the issue arrived!

Please note: db.php drop-in symlink file of Query monitor should reside in a wp-content directory to receive the bug. Hence similar approach to local development should be made in a local environment. Use this plugin to download wp all importer plugin from debug site for local environment: https://wordpress.org/plugins/wp-anything-downloader/

Thanks for the report Shiva!

I can't see anything in the stack trace that's specific to Query Monitor. Can you provide some more info please?

@johnbillion Please install these WP All Import plugins and Query Monitor with drop-in db.php enabled:

• wp-all-import
• woocommerce-xml-csv-product-import

Now follow these steps to replicate the bug within WP All Importer:

• Go to the "All Import > New Import" page.
• Upload the "sample_products.csv" file and select Create new "WooCommerce Products".
• Continue to Step 2 and again click on Continue to Step 3.
• Just drag the "name" as a title for testing.
• Continue to Step 4 and the issue arises.

When I remove the db.php drop-in everything works perfectly. Thinking so I contacted first to the WP All Import team but they said it's a known issue and I can report it here. Please lemme know if you need help replicating the issue.
