I’ve found a nice error today on our Sharepoint implementation.

The error appear only on one site “SiteA”.

Description of the error:

By going on the Site settings on the top of the page you have a breadcrumb, by clicking on the over right site in it (SiteA), the destination was supposed to be(http://mysite/SiteAA/SiteA/), which in fact is resolved by Sharepoint to http://mysite/SiteAA/SiteA/Pages/Home.aspx but in our case the result was a nice error 500 page.

Resolution:

No real solution because I didn’t get the real explaination on that error, the workaround was to go the site permission and to inherit the rights of the parent site and re-setup the rights after.

I don’t get the real reason on that error but a hotfix exist for that: http://support.microsoft.com/kb/936867
