Actually I am using Version 4.13.3, which I installed from Ubuntu software center yesterday. Then, when I print a timetable week, the week days (Mo, Tu, We, Th...) are not shown on the top. Also in the small month calendar left on the top these week days are not shown. Reproducible: Always
check the URL with the printed PDF file
Can confirm here ( korganizer-4.14.3-1.mga5 on KDE-4.14.3 on Mageia Cauldron x86-64). By using File → Print → Print week → «Print…» → to file, I am getting only a week calendar without the days titles.
This bug has never been confirmed for a KDE PIM version that is based on KDE Frameworks (5.x). Those versions differ significantly from the old 4.x series. Therefore, I plan to close it in around two or three months. In the meantime, it is set to WAITINGFORINFO to give reporters the oportunity to check if it is still valid. As soon as someone confirms it for a recent version (at least 5.1, ideally even more recent), I'll gladly reopen it. Please understand that we lack the manpower to triage bugs reported for versions almost two years beyond their end of life.
Seems fine on fedora 26 x86-64. Resolving.
