2.0.24 to 2.0.26a error makes VM disappear from menu

I am not sure why this happens.  I have updateded Joomla without any issues and this is my environment.    I attach 4 screen captures that show the issue in detail.   Thank you.

SOLVED. Thank you for all the hints. I now have 2.0.26a, but I would like to share my findings:
a) I managed to install VM 2.0.24 but I had first ti change all file permissions to 777
b) If I try the 2.0.26a update before I  reset all permissions to 775, the update works.
c) I am on Centos 5.10 under plesk 10.5 which even though I have added apache to the psalcn group, for some reason the joomla folders are unwritable.  On an older Plesk 9.5 instead everything worked with the psacln group.  I had to chgrp -R apache * and then everything is OK.
d) I do not have Xmap
So , although I do not have a perfect diagnosis of the problem, it is certainly related to permissions.   Permissions have been an ongoing issue since Joomla1.0. on Linux.
I hope it helps.

Thanks for your feedback, but

This is not right. It is to 100% your permission configuration. Be aware you have permissions by apache and permissions by the file system. You also should know that you can install php for apache in different modes (as mod_php or was fast-cgi).
