Scipt install error

Hi,

Using VirtualMin GPL on CentOS 6.9

When I try to install a script via “Install Scripts”, f.e. RoundCube, it all goes well until the RoundCube installation.

Now installing RoundCube version 1.2.4 .. Failed to extract source : Uncompression failed : sh: line 0: cd: /var/webmin/.webmin/355203_6656_2_script_install.cgi: Not a directory .. failed! See the error message above for the reason why.

I tried SquirrelMail also, same error but different source:

sh: line 0: cd: /var/webmin/.webmin/639868_7010_2_script_install.cgi: Not a directory

Somebody knows how this could be solved?

Kind regards,
Age
