cannot edit others post

[Harshit]

I was using mybb 1.6.10. Recently i took changed files of 1.6.11 & upgraded to mybb 1.6.11, then took changed files of 1.6.12 & upgraded to mybb 1.6.12

Today when i tried to edit a users post then i got this error

yo cant edit posts because you don't have permission to do it

I am the only admin of the forum, then why i can't edit any users post? I can only edit my own post.

Thanks

Ok, i got the problem. I was checking the plugins by disabling them then i found that by disabling this plugin, everything was working fine.
http://mods.mybb.com/view/hide-content-until-reply

I have installed its new version i.e. Hide Content Until Reply (1.9)

How to fix this problem ?
