This version contains only fixes to run the SCP2 on Plesk 11.5. If your system already run with Plesk 11.5 the autoupdate of the SCP2 won't work. In that case you have to make a fresh install of the SCP2 incl. a recompile of the wrapper.

Alternatively I offer a little shellscript that will update the SCP2:

1) Navigate on the shell into the SCP2 directory (e.g. /opt/psa/admin/htdocs/scp2)
2) wget http://www.haggybear.de/download/scp2_psa11_update.sh
3) chmod 755 scp2_psa11_update.sh
4) ./scp2_psa11_update.sh

Now the SCP2 should be able to run on Plesk 11.5
