Site collection creation fails without any obvious reason
I experienced a wired problem.
The creation of a new site collection fails on one web application. On other web applications it works fine. But what’s the reason?
After hours and hours of digging and trying I determined that I created a site collection within this web application without setting a template. Entering that site collection by browser it asks to select a template. As long as you do not select a template at this site collection you can not create further site collections on this web application without getting an error.
Wired by obviously true🙂
