Confluence 5.2.4 has no option to share pages

In our 5.1.5 Confluence instance we had 3 options in the top corner of each page. They were Edit, Share, Tools.

Now after our upgrade to Confluence 5.2.4, the only options available are Edit, Watch, Tools. We do not have a Share.

I believe this is a bug because this has not happened to anyone else, nobody has mentioned it and according to some screenshots, I should have 4 options ( Edit, Watch, Share and Tools. )

Here is that screenshot:

Thanks I hope we can get this figured out.
