Hello,

I recently received a notification from Follow.it, the service I use to alert users about new blog posts, stating that my RSS feed is invalid. I've been using this service for several years without any issues until now. Follow.it recommended validating my RSS feed using W3C's Feed Validator:

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

but my feed did not pass validation.

To further investigate, I created a test site from scratch, including the blog, to confirm the issue: https://aleksey.homeip.net/test

I then attempted to validate the RSS feed https://aleksey.homeip.net/test/blog/x5feed.xml Unfortunately, it also failed validation.

However, I was able to successfully subscribe to my test feed using Thunderbird's RSS reader with: https://aleksey.homeip.net/test/blog/x5feed.xphp

I recently updated my WebSite X5 Pro to version 2025.1.4, but I'm unsure if this issue is related to the update.

Any insights or assistance would be greatly appreciated.

Best regards, Aleksey
