The 404 error in WooCommerce can occur due to various reasons, but the most common cause is a corrupt .htaccess file. Fortunately, there’s a straightforward fix for this issue:
If you can still log in to the WordPress backend:
Go to Settings > Permalinks.
Click “Save” at the bottom of the page (no need to change anything).
Flush the cache for good measure.
Verify if the issue is resolved.
If you can’t log in to the WordPress backend:
Access your hosting dashboard and log in.
Navigate to the “file manager” section (the exact location may vary depending on your WooCommerce host).
Make a copy of the existing
.htaccessfile.Rename the old
.htaccessfile (e.g., to.htaccess1).Copy and paste a default WordPress
.htaccessfile into the new.htaccessfile.Save the new
.htaccessfile.If possible, flush the cache from the hosting dashboard.
Verify if the issue is resolved.
Remember to test thoroughly after making any changes.
