This page contains the following errors:

Hi Ezra, usually when there is output BEFORE the starting XML declaration, it is coming from another plugin. Or you might have WP_DEBUG on and there is a notice printed before anything else.

I can probably tell you more if you can share a link to your faulty sitemap ??

Hi there.

Wow, many thanks for the quick response.

Here the link as requested.

– I dont have “debug” active.
– disables all the plugins, but I still get the error.

Hope this help.

There is indeed something before the opening XML tag: a blank line.

This blank line at the beginning is also visible in your regular page source code (not so dramatic as it does not result in an ugly error there) as well as in your RSS feed source https://yeboworld.com/feed/ where it does produce the same error.

To make sure it is not my plugin, disable it and revisit the RSS feed.

Then check via FTP some essential files in the following order and make sure there is NO blank line before the opening <?php tag:
– your themes functions.php (also make sure there is no echo statement living outside a function, that could cause this blank line)
– wp-config.php
– index.php

Hope that helps you find the cause ??
