I have had issues with the component lately, and did a update to Joomla 3.8.3 lately. I deleted, reinstalled and set up a 2.1.16 version of B2j, which seemed to work. When I went to the client website this morning and clicked the link, I got a blank page with no content in it. Need some help, as this is a large Swedish exhibition company and they are depending on customers enrolling online, and we have had B2J working for a couple of years without any problems.

This is the page, that had a working form till this morning:
