Invalid RSS feed – permanent error

    Hi,

    a few days ago my website RSS feed started to generate errors. When checking there:

    https://validator.w3.org/feed/

    the feed, which is:

    https://www.superkierowca.pl/feed

    the W3C validator says that RSS feed is invalid and shows a list of errors. As long as MailChimp uses the same validator, these errors make my website’s RSS feed useless.

    In the meantime i did not change anything to the website. The only one change for sure was that a WordPress updated itself which may cause the issue.

    Any clues on that?

    Best,

    Mike

    Try:

    – deactivating ALL (yes all) plugins temporarily to see if this resolves the problem (plugin functions can interfere). If this works, re-activate them individually (one-by-one) to find the problematic plugin(s).
    – switching to the unedited default Theme (Twenty Sixteen, etc.) for a moment using the WP dashboard to rule out any theme-specific issue (theme functions can interfere like plugins).

    I will do that for sure, but… There is a cache somewhere between WP and W3C validator. Even if I apply some changes (i.e. publish an article, turn on some RSS formatting plugin) the W3C keeps the old version of feed for a long time. That makes such examining proces somehow hard. When I check the RSS feed in the browser all the changes are there but on W3C they have their own memory for the feed or something. I will try to switch off what’s possible and post about the effects.

    Issue resolved – there was a code of a symbol invisible in WP editor between words in the post content. I was able to see it after pasting the content to txt editor outside WP. I discovered it by Chance, so if you see that when you put a cursor in a white space between words and the arrow on keyboard needs to be pushed twice to move the cursor – there must be something invisible in your post content code. Copy it, and check out in txt editor outside WP.

    Error description from W3C RSS validator:

    XML parsing error: <unknown>:627:88: not well-formed (invalid token)

    and the line 627:

    <p><strong>– szerokie tylne s?upki ograniczaj? widoczno?? do ty?u ? jak w niemal ka?dym kombi tylna szyba ?atwo si? brudzi.</strong></p>

    Seems valid? Nope ?? If you get this kind of an error, have a check your content in outside WP text editor.

    Best to all,
    Mike
