Members2 Pro, Support System and Permalinks issue

I have a new site on my localhost with a few plugins activated.

Support System and Members 2 Pro run from a subsite.

In Permalinks settings we have this options:
Plain
Day and Name
Month and Name
Numeric
Post name

If permalinks are set to Plain, I can view the front end pages but then I have this message:

Your Permalink structure should include the Post name to ensure Membership 2 is working correctly.

If I use any of the other options, I cannot view the front end pages :

Object not found!

The requested URL was not found on this server. The link on the referring page seems to be wrong or outdated. Please inform the author of that page about the error.

If you think this is a server error, please contact the webmaster.

Error 404

premium.localhost
Apache/2.4.7 (Win32) OpenSSL/1.0.1e PHP/5.5.9

I am still in the first steps with these plugins settings and noting been set up, members plans nor support categories, etc. just the pages they created upon activation + wp original sample page. Using the default 2016 theme

If I network deactivate one or both plugins, I still have the same options as above, I can only view pages in Plain mode.

I wonder if this is a bug or compatibility issue between this two plugins as a few days ago I was told the option to run M2 from a sub was not possible? Seems as it has been added as I was able to choose which site to run M2 from and M2 installed its pages onto the sub.
