Hi,

i installed ushare 451 on a 4.7.1.1 umb installation.

All seems ok, but i get this error when i try to add a xslt file.

Removing ushare, make me add xslt files again.

Also when trying to Authorize facebook i get an error:

Facebook authorize error

{
   "error": {
      "message": "Invalid redirect_uri: Det p\u00e5givende link tillades ikke af applikationens konfiguration.",
      "type": "OAuthException",
      "code": 191
   }
}

Error when adding xslt files:
