Hey Heiko,
So this is via SC on the front end?
You may not know if the behavior is due to recent changes, but were there any recent changes? It will help me troubleshoot if I have this bit of information.
Can you list out the Add-Ons that you are currently using? I am interested in seeing if an Add-On that you have installed may effect entries, so a list of those would be great.
There is not way to disable all the Add-Ons, and there would be data loss depending on the Add-On, but that’s not always the case. Really depends on the Add-on.
Once I have a little more information, maybe we can get to the bottom of this.
It may also be much faster if I get a log in from you and take a look. If that ends up needing to happen, is that okay?
Thanks,
