XML Parsing Error: | Troubleshooting All in One SEO Pack Pro | Support | Semper Plugins

Hi

I got a strange error for the first time on one site (using AIOSEO Pro on a few sites without any issues)

After updating the sitemapi get the following message:

Click here to view your sitemap. Your sitemap has been created and changes are automatically submitted to search engines..

but when i click on that link I get the following error message in the browser.

XML Parsing Error: XML or text declaration not at start of entity
Location: https://greeniefy.com/sitemap.xml
Line Number 2, Column 1:

Already tried reinstalling the plugin, but without any change

Any hints are highly appreciated 🙂
