Secure all but the home page...

Log in to the admin and go to builders. Select navagation, click on the link, near the bottom you will see guest and member, select member only. It's that simple. Have fun.

Not that simple.  Nice try, but his post stated he already did that and it hid the menu.  Not what he is looking for.

Here's the issue, the site is most likely running in Free Mode.  This makes everything on it operate as if every person (member & non-member) is a paying customer and opens all parts of the site up to them.

So, what do you do to fix this?  After all, he wants to lock it down but doesn't want to hide the full menu, and in the event that someone knows the URL to a page (such as yoursite.com/chat.php) then they are in.  Not a good solution.

Here's the trick for you.

1.  Login to Admin Panel & Go to Settings - > Membership Levels

2.  Turn off Free Mode and Promotional Memberships, we want them gone.  In the end they are more of a pain in the arse than they are worth.  (Don't worry, you can still have a free site, just doing it a different way.)

3.  Look down the screen, see Membership Levels and where it has "Standard"  Go ahead and click on "Standard"

4.  Below it, you will now see a list of items they can do and at the top of the list a drop down menu.  Go ahead and click on the drop down menu and start giving all the permissions you want them to be able to do. 

•     Note here:  Certain items by default, like sending messages, greetings, viewing profiles and so on will have limits on them.  You will need to change these limits from their numerical value to unlimited (You just type the word unlimited in the box where it has a number) and this will enable the site to run in free mode without having to be free.  I know, a pain in the arse, but this is the best way to get what the Opie has asked for.

What FRSAdmin is referring to is locking down a menu only, it will not deny access to pages as the Opie has requested, only by setting membership levels can you limit access to pages. 

5.  You will need to next click on Non-Member and remove all items from their list of things they can do and add those you want them to be able to do. 

Not that hard guys and definitely much more secure than locking down just the menu.

I'll try this now! Great tip! I've been having issues with greetings being sent at random.

If I would have read the message throughly I would have caught that. My mistake, I do apologize. I would have given the same answer, had the same issue.

Figured it out! Thanks again for all your help.
