I've read your project description, and i understand your problem. I can review your server, and most likely fix it. I've over 10 years of experience with managing various OS, so it shouldn't be a problem. Please send me more information about your box by PM, most important information is what distribution you using and what version, also Plesk version could be helpful. For this project i'll need temporary SSH access to your box. Please don't hesitate to contact me with any question or additional information by PM, thanks.
