I'm like a walking Silverstripe bomb!!
I installed a nice new v2.0 installation, and then I killed it again with the same file. I did change some things, apparently not the installation killer.
However, I think this time I have worked it out, and now have changed that file again. However, I now have v2.2.1. In attempting to add the page type to the same location, silverstripe-v2.2.1/mysite/code and flushing the database, absolutely nothing happens. It's as though Silverstripe doesn't see my file. I have checked the file extension and properties and cannot work out what is going on.
Any tips?
