Topic doesnt show up (blank content)

Hi,

One topic doesnt show up. As far as I know, this is the only one on my website.

The topic is this one:

https://rencontre-surdoue.com/groupes/zebre/forum/topic/surdoues-celebres/

I tried to save again the permalink. I changed the topic to draft and published again also. No success.

Do you have any idea?

Best Regards
