.php problem after install

[gkestrel]

hi there followed the instructions to install ubuntu centre and got the phtml problem, managed to solve this by following the advise others had posted. Am now able to log on to the centre and follow the install, install says successful and to click continue, but firefox then asks to open the .php file with screem. any advise or help would be very much appreciated

solved this by uninstalling and then reinstalling as per the instructions for getting apache 2 ready for the net
