osTicket v1.10 (stable) and Maintenance Release v1.9.15 are now available! Go get it now

Configuration Error

Hello Everyone,

I just installed all the prerequisites and attempt to get the website up and running.

Whenever I go to http://localhost:8080/support/ (or any of it's subfolders) I get this error below.

Any ideas? Am I missing something extremely simple?

OS: Windows 8.1
web.config is default

Server Error in '/' Application.
Configuration Error

  • Somehow this was left out.

    Line 3: Line 4: <configSections> Line 5: <sectionGroup name="system.webServer"> Line 6: <sectionGroup name="rewrite"> Line 7: <section name="rewriteMaps" overrideModeDefault="Allow" />
  • Ok, I figured out that system.webServer is defined in applicationHost.config

    Now I'm trying to figure out how to override it.
  • Also I'm using IIS 8.5, please let me know if it isn't compatible.
  • Thanks for the detailed information. I'll check into the shipped web.config file
  • Hello:

    I have the same error but using IIS 7.5, any ideas how to solve it?
  • jnavarrope have you tried removing the web.config files that ships with osTicket?
  • I had the same problem (also using IIS 7.5). It worked fine for months and then suddenly the same error as mentioned above. When I deleted web.config file, everything worked fine again.
