All users who are currently upgrading an existing mambo-phpShop installation with VirtueMart (just install VirtueMart - no need to manually copy something) on a *nix machine, might experience problems with images not displaying or getting a "500 - internal server error".
This has to do with a wrong permission setting in the files install.php and install.copy.php.
So if you have such problem, please check if all of the following directories are readable:
(INCLUDING SUBDIRECTORIES!)
/components/com_virtuemart/
/administrator/components/com_virtuemart/
If not, you must change the permissions on those directories. You
can (and sometimes must) use mamboXplorer for this task. If you select a directory for chmod, mamboXplorer
changes the permissions of all files and subdirectories in it.
Because of this bug and another bug found in the session / cookie management, another release candidate will be released today.
