Yes that happened because I didn't just overwrite a bunch a posts from the "Capacity" thread in Deluxe with "this post has been deleted by the webmaster", I actually deleted them entirely from the database.
I just realized this morning that the program isn't set up for that kind of situation and a browser refresh should clear that up. I now have it on my to do list to change the index page to look out for that rare situation but I haven't made that fix yet but I will.
When you see things odd things like that be sure to refresh a few times, sometimes that will clear up any issue. Also if you still cant get into that thread be sure to try clicking on the underlined Thread # and not a wash-rinse-spin button.
Eugene, without the actual text of the error message there isn't much I can do to research that. Next time if you wouldn't mind copying that error message and sending it to me I'm sure I can fix whatever caused it.
Thanks everyone!
