problems after taking live

I've just taken my development site live. the existing albums are all rendered in the very fine way we're used to, but I can no longer create functioning albums - not to mention adding pictures from the repository.
when i create a new album, I get the following error message:

    * warning: mkdir() [function.mkdir]: No such file or directory in 'root'/sites/all/modules/gallerix/gallerix.module on line 765.
    * warning: chmod() [function.chmod]: No such file or directory in 'root'/sites/all/modules/gallerix/gallerix.module on line 766.
    * warning: mkdir() [function.mkdir]: No such file or directory in 'root'/sites/all/modules/gallerix/gallerix.module on line 772.
    * warning: chmod() [function.chmod]: No such file or directory in 'root'/sites/all/modules/gallerix/gallerix.module on line 773.
    * warning: mkdir() [function.mkdir]: No such file or directory in 'root'/sites/all/modules/gallerix/gallerix.module on line 774.
    * warning: chmod() [function.chmod]: No such file or directory in 'root'/sites/all/modules/gallerix/gallerix.module on line 775.

these are the lines that set the permissions of the directories which correspond with the albums. the permissions of the "gallerix" and "gallerix/albums" directories are set correctly.
The problem seems to be that gallerix does no longer create the necessary directories. when I try to add pictures from the repository to a new album (notwithstanding the error message), I get the message that the upload fails because the target is not defined correctly.

kindest regards,
