Error 500 – admin-ajax.php

    Hi,

    I am experiencing a critical issue with the YITH WooCommerce Compare plugin on my WordPress/WooCommerce website. When the plugin is active, I encounter 500 or 403 errors on /wp-admin/admin-ajax.php, which causes AJAX-based features to fail across the site. Disabling the plugin immediately resolves the issue.

    The error persists as long as YITH WooCommerce Compare v.3.0.0 is enabled. I rollback to v 2.48.0 and don’t give error.

    Could you please assist me in resolving this issue?

    regards

    Hi and thank you for reporting!

    Sure, I’d be happy to assist; do you think you can enable error logging and post here the specific fatal error you’re experiencing when the plugin is active?

    This would greatly help with debugging, as I can’t see the same issue on my local installation.

    Hello there,

    The problem seems to be due to a feature provided by your theme. To be sure, could you please test this with a default WordPress theme like 2025?

    We’ll be waiting for your response.

    Best regards.

    Hello there,

    In that case, I recommend contacting your theme’s support to verify the issue, as looking at the error details, it appears to have some sort of custom integration with our plugin.

    Let us know any news.

    Best regards.
