Unable to update HTTPRequestHandler

  
Hello, i recently tried install this on my 8.0 service Studio, wich i didnt notice that its not compatible with 8.0 version. So after installing the Facebook component it downgraded some extensions like HTTPRequestHandler and eSpaces. I tried revert the effect updating 1 by 1 extension and eSpace. Apparently didnt help because i keep getting this error: 'AddMetaTag' Action is incompatible with the 'HTTPRequestHandler' extension definition. Please update it. Each time i try open in browser an application (yes now im getting this error in all applications).
Any help will be appreciated, thanks in advance.

Cheers.

PS: Here is the full log:

Fixed the problem.
Apparently republishing old versions wont fix the issue so i deleted completely the extension httprequesthandler and uploaded it again.
 
Attached a functional version of this extension for the people with the same issues.
