SVN Import: "Error: Could not open the requested SVN filesystem"
If you are in a Plesk world..
Solution: Disable custom error docs for your domain. To do so, log in to Plesk, navigate to the domain and uncheck the "Custom error documents" box in hosting settings.Alternativ solution: Create a repo named error (or error_docs or whatever you find in the logs).see : http://pnpq.blogspot.com/2011/11/apache-svn-could-not-open-requested-svn.html?showComment=1324510115093#c5273051064616678938
We solved the problem, but the solution is a little bit messy and disappointing.
We moved repository parent to a path, with full read/write permissions for apache, authentication files were moved to apache configs, after all that it works.
I suspect it was matter to exclude plesk from webdav access.
Is this a problem of repo format (BDS Berkeley DB or FSFS)?
If so, see Subversion FAQ How do I convert my repository from using BDB to FSFS or from FSFS to BDB?
