Just installed CMSMS 1.6 for the first time, and trying out a new hosting company at the same time.
Installation was a breeze! I couldn't believe it - I've installed about 30 websites elsewhere and it was so painful compared to new host.
That's the good news

After installation, I created a new Page, and when it appeared I was unable to choose the Template.
Is there a checkbox somewhere now where I have to specify I want to be able to choose Templates on every new page?
I generally have several templates per website, so being able to choose the template on-the-fly is how I've been using CMSMS for the past few years.
Here's a snapshot of Ver. 1.5.4 and Ver 1.6, to show the missing 'Template' menu:
Menu: Content / Pages / Add new content:

Can anyone shed any light?
Many thanks in advance!
