Unable to retrieve content

Getting errors when trying to get full text of this feed on my self-hosted instance (running 3.9.13): New Times San Luis Obispo

Error displayed is:

This page contains the following errors:

error on line 2 at column 1: Extra content at the end of the document

Below is a rendering of the page up to the first error.

When I pull this on the hosted version, it works fine:
https://ftr.fivefilters.net/makefulltextfeed.php?step=3&fulltext=1&url=https%3A%2F%2Fwww.newtimesslo.com%2Fsanluisobispo%2Frss.xml&max=3

In going through the articles it seems like it’s this item that causes the problem on my instance:

(But again, that article seems to work fine on the hosted version.

Any help is appreciated!

Same problem as always. Your PHP version is too new. You should consider to use PHP8.2 instead.

I wrote a config to prevent predicting the article body. Update your patterns

Thanks for the pattern update!

Is there a roadmap for moving FTR to PHP8.3 somewhere?
