This will help us isolate whether the issue is with the PayPal Payments plugin alone or if it’s a conflict with another plugin. Here’s what you should do: 1. Disable all plugins except for WooCommerce and PayPal Payments. 2. Check if the problem persists. If the error disappears, this indicates a conflict. 3. To find the conflicting plugin, enable each plugin one by one and check for the error after each activation. * Once you identify which plugin is causing the conflict (if any), please let us know. Please try the above steps and let me know the results. * Kind Regards, * Krystian * Plugin Support [Krystian Syde](https://wordpress.org/support/users/inpsydekrystian/) * (@inpsydekrystian) * [2 years, 2 months ago](https://wordpress.org/support/topic/critical-error-642/#post-17404749) * Since we have not received any further communication from you, we are assuming that your issue have been resolved. * Therefore, we mark this thread as resolved.

This situation outlined in the first post is ongoing and this plugin is implicated. This is according to my dev and also wordpress. * “Howdy! WordPress has a built-in feature that detects when a plugin or theme causes a fatal error on your site, and notifies you with this automated email. * In this case, WordPress caught an error with one of your plugins, WooCommerce PayPal Payments…” * There is ZERO doubt there is a problem. * Plugin Support [Syde Joost](https://wordpress.org/support/users/joostvandevijver/) * (@joostvandevijver) * [2 years, 2 months ago](https://wordpress.org/support/topic/critical-error-642/#post-17405909) * Hello [@epppppp](https://wordpress.org/support/users/epppppp/) * there could be an issue, but it does not seem that this bug/conflict has been caused by only our plugin. We expect this is a mix of our plugin with another plugin or theme. If this would not be the case, we would have many more reports of this, which we don’t. * If you want us to have a closer look, it might be better to create a [private engagement](https://woocommerce.com/document/woocommerce-paypal-payments/#get-help), so you can provide the system report and possible other details that could help us isolate the cause for this situation. * Also, you never told us what the outcome was of conflict testing, so when you open this private thread, please also let us know about this and add the URL of this thread, so we are aware of the history of this support request. * Kind regards, Joost Viewing 6 replies - 1 through 6 (of 6 total) The topic ‘Critical error’ is closed to new replies. * ![](https://ps.w.org/woocommerce-paypal-payments/assets/icon-256x256.png?rev= 3234615) * [WooCommerce PayPal Payments](https://wordpress.org/plugins/woocommerce-paypal-payments/) * [Frequently Asked Questions](https://wordpress.org/plugins/woocommerce-paypal-payments/#faq) * [Support Threads](https://wordpress.org/support/plugin/woocommerce-paypal-payments/) * [Active Topics](https://wordpress.org/support/plugin/woocommerce-paypal-payments/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/woocommerce-paypal-payments/unresolved/) * [Reviews](https://wordpress.org/support/plugin/woocommerce-paypal-payments/reviews/) * 6 replies * 3 participants * Last reply from: [Syde Joost](https://wordpress.org/support/users/joostvandevijver/) * Last activity: [2 years, 2 months ago](https://wordpress.org/support/topic/critical-error-642/#post-17405909) * Status: resolved
