Application run time error in plesk panel
1. Show Details: To see the actual error message (it's hidden!), find your application's configuration file (often named "web. config") and change the <customErrors mode> to "Off". But be careful - switch it back to "On" after, as this reveals errors to everyone!
2. Read the Error: The message should point to the problem: Missing files/assemblies. They might be misconfigured or missing dependencies. Search online for the error message for solutions. Coding error? It might mention a specific line of code, indicating a bug. Search online or consider contacting the developer for help.
