Recently, I was logged in as a user with steward rights on the beta cluster (User:Sau226) which has been granted local administrator on a wiki (deploymentwiki) . When I opened a spam page in a new tab after seeing it made in Special:RecentChanges and proceeded to change its protection level it gave me an error and said I was only allowed to view the page and editing of the level was for administrators only. A simple page reload resolved this but I was wondering if this is a software or code issue or simply a client side issue.

Steps to reproduce this bug:

1. Wait until a user makes a page or make one yourself using Special:RecentChanges to find out.
2. Open the page in a new tab and delete the page
3. Try to protect the page as administrator creation only

The page will then show that you can only view the protection level and editing is restricted to users in the group 'administrators'. The top right hand corner which normally has your user name etc. will read not logged in. A while later your username will drop down and a simple page refresh will grant you the ability to change the level.

Ideally, the page would allow you to change the protection level straight away and not need to show you view and then you have to refresh the page to enable editing of the protection level.

I am using Google Chrome (latest stable release) x64 in incognito mode on Windows 10 Home and have also suffered this error on my primary pc (Google Chrome, latest stable release in incognito mode on Windows 7 Ultimate). Third party sites are allowed to save cookies (sites can set and use cookies etc.) If it helps I also use a privacy extension called disconnect (disconnect.me) which is enabled in incognito mode on both my computers

Thanks,

Edit: added qualities of a good bug report
