XML error: Reserved XML Name at line 2, column 38

Curiously, there was no closing ?> but I’m not sure if that is relevant to this problem or not.

It isn’t relevant to your problem. In fact, it’s not a problem at all.

Is this an issue with your RSS feed? If so, a link to your site might help.

Upon further inspection it appears the XML error was a combination of two things… WP 2.9.2 and a several versions old plugin (All In One SEO Pack). Upgrading the plugin made the error go away.

So for me this is solved.

Bumping this one!

I’ve done a “package” of wp-sites/blogs for a company.
All of them are updated to the latest version of WP, and all the plugins are updated.

Take a look at: https://www.marialangen.se/ it should display the RSS feed of “Sverredal & Langen” with the adress: https://www.svelan.se/?feed=rss

This is not working as you can see.
What I’ve done so far:

I’ve turned off all the plugins on svelan.se, and suddenly the feed started to work on some of the other wordpress-sites, for example: https://www.krisinstitutet.se/

But on https://www.marialangen.se/ and https://www.dromwebben.se/ it still dosnt work.

I’ve looked for blank rows in my wp-config, function.php.

If I try to validate the RSS feed it says: https://validator.w3.org/feed/check.cgi?url=http%3A%2F%2Fwww.svelan.se%2F%3Ffeed%3Drss

So it looks like the first empty row is causing this?
Any more ideas about where to search?

Solved!
