Hello, Not sure why this started to happen, but I built my website and haven't had to change anything for about 3 months. I opened dreamweaver cs5 to make some changes, and none of my .php files would open. No error messages or anything, it just looked like it was going to open the file, then nothing. I thought since I made the site in cs4, maybe for some reason it wouldn't be compatible, so I loaded cs4 back on my computer, does the same thing. I even went as far as copying the code from a browser, and making a new file from scratch. I saved it, then it wouldn't reopen. Strange, any insights?
