Project Euler Forum

I tried several time to post on some problems threads ( 21, 22 and 26 for exemples) but each time I click on "Post Message" i'm redirected to the end of the thread but I can see my post.

My message can be previewed correctly and even just "Hi" as a post does not work.

Could have I been blocked for any reason? Is it linked to my private status?

Thank you for your help!

Panic not! It's nothing to do with you. I think I might have identified the issue. It was caused by a script I hadn't updated properly as part of the Site Maintenance (December 2025). Can you try again?

It works well now, indeed!
Thank you!
