I have enabled SSRS 2008 R2 integration with my SP2010 farm. I have created new sites on which SSRS is working perfectly.
Now there is a particular site (existed before SSRS was installed on farm).
On this site collection if I try to enable SSRS Integration feature. I get error
I googled on this error and people have solved it by deleting sites or subsites... but in this case this is an existing site and I cannot delete any subsites.
Edit:: On my farm I found most sites already have this feature enabled. If I create a new site it also have this feature enabled. Its only on this particular site collection this feature is not enabled and it also fails on activation. I want to enable the feature without deleting anything.
I suspect that this is a site which was migrated from old 2007 environment.
How do I resolve this?
