Can you explain what you mean by a query having only a single placeholder? I'm kind of confused by that
when debugging, i have it print out the actual query as well so i can see which query caused the error...
an example of one query that caused the bind_col error was this:
SELECT user_id, username FROM users WHERE purch_perm_id != 1 AND deleted != 1 ORDER
BY username
the weird thing is, if i hit refresh, the page will load fine and there won't be any errors
