cannot reply to postings

[thewalnutguy]

When I click on "reply" to a posting, I get this error

This Page isn't working
Forums.woodnet.net is currently unable to handle this request
HTTP Error 500

I've used the reply function previously, this just started happening yesterday

update 9/21
I've found that that I can do a "New Reply" successfully, but still cannot do a "Reply" without getting the HTTP Error. Downside is that what gets posted does not include the original post to which I want to reply, but that's better than not being able to reply at all

Edit: the mess just above this is from using New Reply button.

New edit: most of the metadata that was showing before is gone now, if you're wondering about my first edit

<p>Admin is working on the problems. Some of them are coming from issues associated with changes in the default settings of the forum software. A software version update has been installed this week.</p><p><br></p><p>If you have access to the Off Topic, there are 3 stickied threads with reports of problems.<br></p>
