One of my websites recently had problems with the PHP news parser.
For many years, it worked fine. However, a while back it started acting up. See the attached image of a screenshot.
And since the PHP parser was the first block of code on the page, since it didn't work, the whole page didn't work.
Now I am trying to narrow down the problem. I am not good with PHP.
The hosting company's Tech Support guy told me the code is bad, even though I made no changes. (Why would it work fine for years and then randomly stop?!?!)
Somebody else suggested the problem might be with FeedBurner, because the feed is coming through FeedBurner.
The error message is, "XML error: not well-formed (invalid token) at line 5"
Does this information indicate the problem is with the PHP code, or the incoming feed?
Any direction/advice/guidance is appreciated.
