Hi,
Do I just replace all these files from the .opm files? What is the difference between a red x and a black x?
The black x means that the file which should be installed is not there,
it's most likely that it could not be installed due to missing
permissions for the webserver user.
The red x means that the files which are installed do not match with
those which should be installed. You can have a look at the difference
by clicking on the red x.
Since the reinstall-button doesn't help you should try to install the
opm via command line:
