I have a system that is only used by a few people to enter records for a program they administer throughout our service area. One of the things they record is what's called a session, a single visit, indicated where it was held, which grouping of sessions it was a part of, when it took place, and what families and children attended. This was working flawlessly up until recently when the user reached out to me in a panic because she thought she had deleted all the sessions. This would be impossible as that user isn't equipped with deletion rights. So I logged into the system and the records were still there. It had paginated the results so I clicked on page 2, as soon as I did this the page said, "no records" and the pagination buttons disappeared. So I hit back on my browser, still no records. I tried going through the menus back to the sessions list, still no records. So I logged out and back in, now the records appeared again. I've now found that if I try to change anything on the list while viewing it, it will make the records disappear from view. Change the number of displayed records, they disappear. Try to apply a filter, they disappear. And nothing you do will make them return besides logging off and back on. Other lists within the same site do not express this behavior, filtering and pagination behave normally. This list has several joined tables but that's not unusual for the entirety of the site. This list has no pre-filters whatsoever. I'm running Joomla 3.9.1 with Fabrik version 3.9 I'm at a complete loss, I have no idea how this is happening or how to fix it? I can't say specifically that the problem started after an update as only a few people use this system and only just complained. Any guidance or suggestions would be greatly appreciated.
