Change owner of a sharepoint site

Question

My company has recently started sharepoint for collaboration. Now I created sites and subsites for all my projects. And that time I created new groups for owner, members and visitors for each subsite. But later I realised that the owner group can be same for all subsites. So I deleted the owner groups for 2 of my sites. Now I am unable to create subsites or delete those sites. How do I find who is the owner and how can I add myself as the owner for these sites. Any help would be appreciated.

Answer 1

Try going to the /_layouts/permsetup.aspx page on each of the sites to add the new owner group.

For instance, if you had a site with the url http://testapp/testsite/, you would go to http://testapp/testsite/_layouts/permsetup.aspx
