Spoiler tag

[Arilita]

I've noticed today that while the spoiler tag works normally (

like that

), it isn't recognized in my posts left before TES Source went down (like here, or here, or here). I'm totally sure that I haven't edited them since the time they looked OK. And it happened not only to my posts (like here, or here, or here)

 

I suppose editing posts without changing would help, but that means everyone should edit one's old posts. I'd like to know if there's a way to fix all the old spoilers at once, and if it is, will the site owner do it?

Thanks in advance.
