Unable to add a feed XML error

[Dav-d]

1. Environment

• Device: [Huawei p30]
• OS: [Android 12]
• APP: [0.10.1]

2. Describe the bug

I use a freshrss self hosted.

Each time I want to add a feed, I get an XML error : for example:
Invalid XML: Error on line 11: At line 11, column 454: not well-formed (invalid token)
With site: https://www.lefigaro.fr

Same issue with adding /RSS or /feed

Tested on a lot of websites. I have to use another app to add my feeds like readrops. :(
