PHP SMS Twilio Project -- 2

Description of the Website This website sends text messages using an interactive php calendar. Twilio provides an API that sends and receives text messages. This site (our site not [login to view URL] ) has a feature to send redemption codes and utilize logic to filter erroneous text messages sent. The site is also able to respond to incoming text messages and send specific text messages to incoming requests. This is a SUBSCRIPTION based service that charges the customer a recurring payment through PayPal Pro. The payment solution is about 80 percent completed and needs some testing to complete. The customer is charged a monthly amount for their package and they are assigned credits to send and receive text messages. The site will also need a Demo feature. This should be a walk through of the sites features utilizing sessions. All of the features on the site should me "clickable" but unless they are logged in, no action is made to their request. The site currently has a log in system that protects the interactive calendar. Once a visitor signs up, they are able to schedule text messages from the calendar. With the Demo feature, the unsubscribed visitors will be able to see and interact with the calendar but, at the last step before a text message is sent, a prompt will thanks them for viewing and direct them back to the home page or allow them to visit the services page to order. This should be a very simple feature controlled by log in sessions. This site has been moved from a development server to a live server available from the internet. All databases have been transferred and tested. There are some minor directory path related issues that will need to be resolved from the move but the majority of the features/functions are working on the new server.
