Modifications to existing MT4 EA

I am looking for an experienced programmer to perform the following tasks:

Fix bug in license check

The EA validates the license by sending a request to our server. A php script on the server then checks if the account name/number combination exists in the sql database. The license check works correct but only for demo accounts. From some unknown reason it does not work on real accounts. Your job is to find out what is the problem and fix it. As it works well for demo accounts I imagine that it is some minor bug.

Make some modification to the license check

Right now the EA checks the 'order id' of the user, the 'account name/number combination' and the 'product id'. The license check should be modified so that only the account name/number combination and the order id is checked.

Switch to another db

We use a special db for developing. When everything works correct the information in the config file needs to be updated to make sure the php script performs the license check in the correct db.

Required skills

PHP, MQL

Estimated time requirement

From my previous experience I believe that the tasks will take an experienced programmer 1.5 - 2.5 hours.

Files

Server logins and source files will be provided once we have an agreement.
