I already saw the other questions concerning the same problem, but after trying everything described in the answers there, I still have the problem that my saved print compositions do not show the maps. Not only do they not show in the print composer but also in the printed PDF version there's only white.
As I work with bigger compositions with many maps in one file, it would be great if there is a way to "repair" these.
It was mentioned in Map does not appear upon opening print composer in QGIS that this could happen, if you delete or modify the map layer –
because it didn't work properly I had to remove my basemap content .
Could this be the reason for this problem and if so, is there a way to repair it?

I don't really have a solution for the problem I encountered with the question I asked, BUT I think I at least found the reason why my map didn't show in the print composer:
before printing the PDF, I had to change the coordinate system / projection of my project (it was wrong before) and apparently the print composer didn't recognise my map anymore. I tried changing it back just for printing, but that didn't change anything and it still was not printing my map. So, I still don't know the reason for my problem, but know now, how to avoid it.
