I don't know what's happened.

Administrator/Moderator, I don't know why, but somehow I can't reply to this thread. The error "HTTP Error: 403 Forbidden The document you requested has been locked for a reason." is returned when I click "Preview Post" or "Submit Reply" button. (The same error occurs when I tried to edit some of my posts and to make a new thread in the Learning Japanese section.:?)

That's weird, I am able to reply to it....

How are you trying to reply, with the advanced reply or quick reply function? With wich other posts have you had problems.

Maybe Thomas knows more about it.

Yeah, indeed weird.

I tried to reply to click "REPLY" button on the left side.
And the post I wasn't able to edit is here. As in the post, I edited it once, nevertheless the 403 Forbidden Error was returned when I tried to edit the post again just few minutes later. The same error occured on a post probably a week or so ago, I don't remember exactly which one it was, though.

Maybe try clearing your internet cache and seeing if it isn't caused by some bad cached content.

I was able to reply to it too.

Thanks for your help, guys.
I finally identified one of the reasons for the error. Apparently, this forum refuses a post that has more than 4 embedded urls in it. But there still remains another question "why I can't edit my post". The same error reoccur on here. (URL links might concern this, too?)

EDIT:
I got it!!
1) delete a URL link in the post, 2) edit it, 3) re-add the URL, then I was able to edit my post at last!
