Hello,
I can have this gone through and taken a look at for you, see what can be done.
From the looks of things, there are a number of vulnerabilities in here, and some pretty outdated stuff.
Problem #1 (what is stopping install?):
You're using globals for $install, which is a bad thing. This should be set to either $_GET or $_POST , depending on the call to it.
Like I said, I can go through, take a look at the rest of the stuff, get it up and working for you if you like, will take a couple of weeks to do.
If you'll look at my profile (click the link directly, don't go by what they show in this specific bid), you'll see 100% project completion, 100% positive (5 star) feedback, and a link to my own site where I've done the same for better than 10 years now. Your project will be completed with the same diligence and persistance. Your task will be completed within the advertised period of time, and be given everything needed to be done right.
I look forward to hearing from you and working with you on this project.
Tom Whiting
