Hello,
We apologize for the issue you are facing with the search engine on your WooCommerce store page. A 500 error indicates a server-side problem, which can be caused by various factors. Here are some steps you can take to troubleshoot and potentially resolve the issue:
-
Review Server Logs: Check your server logs to pinpoint the exact error and its cause. This can provide insights into what might be going wrong.
-
Check for Overload Signs: Look for signs of server overload, such as slow response times or high CPU usage, which could be contributing to the error.
-
Verify Settings: Ensure that your PHP version and other relevant settings are correctly configured. You can refer to this guide on upgrading your PHP version if needed.
-
Contact Hosting Provider: If the issue persists after checking the above points, it may be best to reach out to your hosting provider for further assistance.

Thank you for your query, and we are so sorry about the trouble this must have caused.
Please head over to WordPress Dashboard > Rank Math > General Settings > Breadcrumbs and make sure that the search format has the following:
Searching for %s
Please note that the %s
cannot be changed, only the other portion of the text can be modified.
Don’t hesitate to get in touch if you have any other questions.
the search format has this
Búsqueda de ‘%’
Hello,
The search and archive format should include at least the following at the end of the text field %s
and not just %
After that, the error should go away, and the breadcrumbs should display fine on the search and archive pages.
Let us know how it goes. Looking forward to helping you.
Thank you.

No, I get a 404 error. But it only happens on the store page. It works fine on the category pages.
