Hi there!
Receiving an Internal Server Error message is never any fun. Unfortunately, this is a pretty generic error message that can be caused by a few things, but I’d love to see if we can find the culprit here.
It’s possible that there might be a plugin conflict. Try disabling all of your plugins except WooCommerce. Then try testing again to see if the issue persists. If that resolves your issue, enable each plugin one by one while continuing to test until you find the plugin that causes the issue.
If you don’t want to do this on your live site, you can clone your site to a staging environment, where you can test without affecting your users.
If your host doesn’t provide staging facilities, a simple way to do it is using the free WP Staging plugin:
https://ww.wp.xz.cn/plugins/wp-staging/
If you could also send us your System Status Report, it would help us to understand your site setup a bit better.
You can find it via WooCommerce > Status.
Select Get system report and then Copy for support. Once you’ve done that, paste it here in your reply.
Hi Masdemas,
Same problem here after updating.
Trail and error disabling / enabling plugins.
Found that WooCommerce Email Customizer was the problem in my case.
Updated to latest version fixed it!
Thanks for confirming @willemw and @masdemas a conflict test would indicate that on your site.
@masdemas, we haven’t heard back from you in a while, so I’m going to mark this as resolved – if you have any further questions, you can start a new thread.
