updating books generating 500 Error

When in book edit mode using https://www.librarything.com/update.php trying to save edits I keep getting a server Error 500. Started about 12:20 pm EST and seems random because some edits go through and some don't. Tried multiple browsers, same error. Logged out, cleared cache etc. Chrome actually displays the error code, Firefox just returns a blank screen. Making basic edits like assigning role of Narrator, adding published date and Publisher info.

We are looking into these errors.

>2 conceptDawg: It's been about an hour since I got the first one and I was able to go back in just now and finish up the edits I was making without encountering it again. 5 or 6 edits without issue. I have several more to do tonight so I'll track any recurrence and report it here.

Closing.
