We were using a server application called WAMP - Windows Apache, MySQL, and PHP - to run our website. Unfortunately, the program was causing an incredibly large number of errors that seemed to be causing poor server performance and ultimately required rebooting the server numerous times over the past years.
Today I uninstalled WAMP, installed Apache, MySQL, and PHP manually using their individual installation files, and then reconfigured all of the services to work together. Unfortunately, I ran into some problems along the way which is why it took so long to get us back up. Alas, at 11am I was able to finally find the missing puzzle piece and bring the site back online.
So let's hope everything goes smoothly from here on out!!!
