[TYPO3-calendar] No appointments in monthview in 2012

[Bruno Schäpper]

Hi all,

I have a problem that drives me nuts..

Everything works just fine. However, starting from 1.1.2012 no
appointments show up in month view. List view works..

I updated/reinstalled every extension, uninstalled unused stuff, cleared
up my database, updated my TYPO3 Installation and everything.. Nothing
helps.

Does somebody have an advice?? Please ..
