It's several years since I last used my copy of dbmansql.
Now I think I have a project that it would fit, so I have reinstalled it and run a few tests.

But I'm seeing a curious error that is new to me ...
I can't search using the default template becase the search options box near the bottom of the search form reports two unknown tags: idx and sb (see the png attachment).

I'm not sure what <%idx%> represents, but <%sb%> should be a drop-down list of columns in the table, and I cannot imagine why it should be unknown.
I'm stuck again after only five minutes.

Does anyone understand what is going on here?
