While trying to get a site collection in browser, It gave me this error: “Access to this Web site has been blocked. Please contact the administrator to resolve this problem.”
I understand, the site collection is being locked out! Wanted to unlock it by going to the Central Admin website. Central Administration > Application Management > Site Collection Quotas and Locks and select Not locked. But that also resulted in an error.
Hmm… SharePoint doesn’t allow me to unlock the site via Central Admin.
Unlock the site collection using STSADM
stsadm -o setsitelock -url <site-collection-url> -lock none
Yeah, This resolved my issue and got the site back.
