For osCommerce v2.2 ms2 (ie earlier than ms3)
Two contributors have solved the problem of the following error message: "PHP Fatal error: Call to a member function isLoggedOn() on a non-object in C:Domainsdhammabooks.org.zawwwrootcheckout_moneybo okersipn.php on line 19". This was attributed to the fact that the latest Moneybookers payment module was written for versions of osCommerce later than v2.2 ms2 and four files had incompatibilities with the earlier versions.
This present .zip file contains the complete Moneybookers payment module, but this time incorporating all the necessary changes to the four files concerned. That is, it is the whole thing in one, including the original installation instructions. This works nicely on my store. Thanks to those who resolved the original problem.
