Hello. I installed the latest version of the Application Forms and I get this error when adding new fields.
UPDATE `applicationform_fields` applicationform_fields SET `allow_attachments`=NULL,`type`='Text',`options`='null',`multiple`=false,`required`=true,`input_format`='' WHERE id=1
IPS\Db\Exception: Column 'allow_attachments' cannot be null (1048)
So, your application is setting allow attachments to null even though the next line is saying it can not be null. I've had it manually tweaked to overcome this issue but would like to bring it to your attention and get a patch. Is this issue only for me?
