I have a website which is coded in asp. We have upgraded out plesk server from plesk 9 to 12 since then, I am getting a "Internal server error".
It could be that the new version of ASP installed on Plesk is not compatiable with the version of ASP that the website is coded in. Right now we do not have the website only the code, so is there a way to find out which version my ASP code is coded in just so that I can install an older version of ASP on my server to get the website back up and running?
Open your project in visual studio once your project is loading in visual studio click web config file in that you can find .Net framework version.
