Just got a very interesting error in my SharePoint 2010. Not exactly sure how it came to be … but anyways. I was making some PowerShell updates to the site … also restored the site using PowerShell … maybe this left the site locked down eventually.
First I could not edit or add anything to my SharePoint 2010 site. I tried to log-out and sign-in again. Than I restarted the server – this also didn’t help. Than I tried to change the site collection administrators and I got “Additions to this Web site have been blocked” error. Than I was closer to the solution … had to go actually to Central Administration > Application Management > Site Collections > Configure quotas and locks and change the “Lock status” for the site to Not locked.
