At office, we used wiki to share knowledge about projects and technical things. It's a good way to keep, organize and share the information. So I decided to install a wiki on my PC for personal usage.
Take a look around on open source wikis, I decided to install ScrewTurn Wiki on my PC (Windows 7). The reason I try it because it's included in Microsoft Web Platform Installer, so maybe it's good enough.
There are two ways to set up ScrewTurn Wiki: via Microsoft Web Platform Installer, and manually. I tried with Microsoft Web Platform Installer first because it's simpler way to install, just select and click a few options and buttons, and you should have something works. So I did it but had 500.19 error. Then I tried to set it up manually, but had the same problem.
Look into the error message and I finally found out that removing the whole 'configSections' section in web.config help to resolve the problem. Damn it, when there is an installer, I expect that after I click Finish, the software should be on and running.
Anyway, the wiki is running now and I will dig into it.
