Can't reply to thread in Trading Post

First off, I have been a member since 2011 so time is not an issue.

I found a thread in the TP, Private Party Firearms section that I wanted to reply to.

When I click on Reply to Thread, I get a page that tells me :

losttrail, you do not have permission to access this page. This could be due to one of several reasons:

1. Your user account may not have sufficient privileges to access this page. Are you trying to edit someone else's post, access administrative features or some other privileged system?
2. If you are trying to post, the administrator may have disabled your account, or it may be awaiting activation.
3. If you are posting in the trading post, you must agree to the terms and conditions before posting.

I have sent 2 emails to support but had no response.

Under Posting Permissions, this is what I see:

• You may post new threads
• You may post replies
• You may post attachments
• You may edit your posts

I have posted in the TP before, both listing and replying to posts.

Any help would be appreciated.

Look at suggestion #3 in the no permissions text you posted.

Ok, I have done that in the past, but now when I try to acknowledge, all I get is a blank page.

It was probably lost in the great crash. When do you get the white page. When you go to the terms and conditions thread? When you click the reply button? When you submit your reply?
