^^ i get that too. Your editing period has timed out, just click "Report Abuse" and the mod bruvahs should be able to fix anything.
I am facing same problem just now. Says you cannot edit delete your post. Please fix it kindly.
testing
It is workimg for me.
you can edit for 5 minutes, after that you need to ask the mods to do it for you (click on report abuse and type in the changes)
