same here - the column name "false" was not found
I have a red exclamation mark next to "Manage Relational Table" and clicking on it the above mentioned error message pops up, followed by:
The column name "".$_SESSION['WADA_Insert_products']."" was not found.
Nothing is inserted after starting from scratch.
On the update page there is also a red ! next to "Manage Relational Table"
