Asking permission to edit a blogpost?

So there's this page:

https://strike-force-heroes-3.fandom.com/wiki/User_blog:Ivilok_enderos/SFH_3_Hero_customization_guide_(Traits,weapon_%27upgrades%27...wip)

I want to edit it in order to add new data, but i can't. Which is weird because i was able to do some edits there at some point. Do need to ask someone to let me change the page or there's something i'm missing? (Like a cooldown for example)
