Well, that didn't take long.
That's it! The site has been completely converted from ASP.net and Access to PHP and MySQL. Everything is functioning exactly the same as it was two years ago when I submitted it to my tutors.
The only problem is the database. All of my backups contain the same version of the database - the one submitted at the deadline. However, it was still missing the descriptions of several (actually more than 30) stations, so over the next week, I finished researching all the stations and uploaded an updated database to the test server.
Unfortunately, I can't seem to find any backups of that final version of the database. This means that at this moment, almost half of the stations in MÈtEX are missing descriptions. While I could go ahead and open the site right now, I feel it would not give an accurate representation of my work.
Therefore, I will rewrite the station descriptions over the current week. If, by the weekend, I have not finished all of the descriptions, I will open the site anyway, but disabling the incomplete lines.
Of course, I hope I manage to find a copy of this elusive database!
