    I can see a number of other tickets with complains about fatal errors and the like. Do you test the plugin before releasing a new version, as we are talking about a payment gateway, not a random shortcode plugin?

    Thanks in advance!

    Hi @metodiew

    I understand that you’re running into these weird critical errors with the Square plugin which you use for payments. It’s definitely a huge bummer to have these errors pop-up and that too over the holiday season. Let’s see how we can fix these problems.

    I tried testing this with the latest version of Square (2.0.8) along with the latest versions of WooCommerce (3.8.1) and WordPress (5.3.2). I was not able to find any errors as such. I tried doing test transactions, and they went fine as well. With this background, I’m not so sure if the problem is with the Square plugin itself.

    I pored over the system status report you shared to see if I could isolate something that might trigger the problem. You’ve not included the list of plugins in your site, so I’m not sure if you’re on the latest version of Square. Can you update to the latest version (2.0.8), in case you haven’t, and then try disconnecting + reconnecting Square and try checking if you keep running into these problems?

    In case the problem still persists, I’d appreciate it if you could do a full conflict test. This is likely caused by a conflict with your theme or with another plugin.

    The best way to determine if the issue is being caused by a theme and/or plugin is to temporarily switch your theme to Storefront ( and disable all plugins except for WooCommerceand Square. Finally, test to see if the issue is resolved by check if you still keep seeing the Critical Error.

    To figure out which plugin is causing the problem, continue to the next step – reactivate your other plugins one by one, testing after each, until you find the one causing conflict.

    Here’s a more extensive explanation in our docs:

    Tools to help you troubleshoot:

    You can clone your site to a staging environment and perform tests without modifying your live site or impacting customers. Many hosts provide staging facilities, so it’s worth checking in with them. It’s also possible to do it using the free WP Staging plugin. Link:

    If you still keep running into troubles, we’d be glad to take a better look at this for you. Can you create a ticket with us by visiting

    We hope to get to the bottom of this soon. Thanks!
