Fatal error: Uncaught Error

Hi there!

Thank you for sharing the detailed error message following your update to WooCommerce 9.8.5. I understand how encountering a fatal error like this can be concerning, especially when it’s the first time you’ve seen it.

The error “Class ‘WC_Log_Levels’ not found” usually indicates that some WooCommerce files may not have been fully updated or loaded correctly. This can sometimes occur if the update process was interrupted or if there is a caching issue.

To troubleshoot further, if you are using any caching plugin, could you please try clearing your site cache? After that head over to WooCommerce → Status → Tools, and do the following:

• WooCommerce transients – Clear
• Expired transients – Clear
• Clear template cache – Clear
• Capabilities – Reset Capabilities
• Clear customer sessions -Clear

IF you still face the same issue, could you please create a staging site? You can use the following plugin to do so:https://wordpress.org/plugins/wp-staging/

Once you create the staging site, please try reinstalling WooCommerce and see if that works for you.

In the meantime, I’d like to understand your site properly. Please share with us the necessary information below for us to investigate the issue further:

• System Status Report which you can find via WooCommerce > Status
• Fatal error logs (if any) under WooCommerce > Status > Logs.

Please use https://pastebin.com/ or https://gist.github.com/ and share a link to that paste in reply here. Once we have more information, we’ll be able to assist you further

Hi @cfm168,

Thanks so much for following up and letting us know that you’ve cleared the WooCommerce caches and reset capabilities. That’s a great start, and it’s helpful that you’re giving it some time to see if the fatal error recurs.

Regarding the Payments page under the WooCommerce menu appearing blank, could you please clarify whether this page was loading correctly before the update or if it has always been empty? Also, had you already configured any payment methods previously, or is this your first time accessing the page?

Sometimes a blank Payments screen can be caused by a conflict with another plugin or an incomplete update, but I’ll be able to better guide you once I have a bit more context.

As for the red alert with the number 1 on the Payments menu, that typically means there’s a pending setup step that needs attention. When you click on it, does it show any instructions or prompts? Or does it simply lead you to the same blank page?

Lastly, could you please share your System Status Report from WooCommerce > Status > Get system report > Copy for support using https://quickforget.com or https://pastebin.com. That will help us understand your site environment and see what might be affecting the Payments section.

Looking forward to your update so we can help you move forward!

Hi there!

Thank you for sharing the more detials about the issue. To assist you further, I’d like to understand your site properly. Please share with us the necessary information below for us to investigate the issue further:

• System Status Report which you can find via WooCommerce > Status
• Fatal error logs (if any) under WooCommerce > Status > Logs.

In the meantime please try to deactivate all plugin except woocommerce and see if you still face the same issue.

Let me know how that goes.

Hi @cfm168,

Thanks for the update, and I understand how having a blank Payments page can be frustrating—especially since you’ve already configured PayPal and Stripe, and they’re still processing payments fine on the frontend.

To help us dig further, could you please share your System Status Report from WooCommerce → Status → Get system report? You can paste it into https://pastebin.com or https://quickforget.com and send the link here.

Also, just to confirm—have you already done a plugin and theme conflict test using the Health Check & Troubleshooting plugin as recommended earlier? This lets you temporarily disable other plugins and switch to a default theme like Storefront only for your session while keeping your site live for visitors. Let me know if you’ve tried that and what you found.

Once we have that info, we’ll be able to guide you more precisely!
