Hi,
I am alons , a developer at Softaculous.
DosDawg was right about the permissions error. There had been a communication gap causing all this confusion. When he posted his detailed report on 22.4.2010 (we were not aware of the post and read it on 23rd), we understood what he was referring to and released a PATCH on the 23rd itself.
We take security very seriously, so please dont hesitate to contact us if you find bugs.
