Tried commenting out that line, then wiping and rebuilding the database. It doesn't help, I'm still getting the same error. I'm guessing it's because getShowOnLoad() is called in populateFromPostData() on line 269.

So I added "ShowOnLoad" => "Boolean" into the $db array. Now it seems happy.

Is there any reason this might turn out to be a Bad Idea?
Is there a reason this works for other people but didn't work for me?

So my forum was working properly until I tried to create a Category and I got a similar error (see below) So I guess this is not a problem related to Userforms but rather a SS issue with my server configuration.

I am afraid I am going to keep seeing the same error coming up as I develop my site.

As always, any insight to resolve the problem will be appreciated,

Best,
