We are running Kirby on a media site and we are experiencing some issues with the Panel.
Whenever the “Open preview” link is clicked on a page, the panel logs out.
The Preview (New Tab) opens fine but when returning to the Panel tab the login page pops up.
Currently running on 2.5.7 & SSL enabled. Experiencing the same issues with previous panel versions as well, with or without SSL, but cannot determine the reason.
I can’t explain it either. Are you sure that the same thing happens with a plain, unmodified Starterkit? Because what you are describing is a typical issue of strange plugin combinations, user object calls in templates, config changes etc. The starterkit shouldn’t do any of this stuff that could lead to the issue.
