Add Category Hidden

I installed 1.50 with the web installer and everything seemed to go fine.  I did not install the demo stuff.

However, I cannot add categories.  The bottom half of the page, below the SAVE button, is blank.  The URL of the page is /Administration/CategoryAdd.aspx.

Having the browser show source and searching for the SAVE button, I find that below the SAVE button is:

<div id="ctl00_cph1_ctrlCategoryAdd_CategoryTabs" class="grey" style="visibility:hidden;">

The thing to note is the lower half of the page has style "visibility:hidden;".

Okay, now what?  Did I miss something? Is it a bug?  Any insights would be helpful.  Thanks.

have you logged into nopcommerce as an administrator?

When you do goto catalog/categories

On the right you will see the save button and right next to it the add new button.

Hope this helps.
