Drupal 8.x

Hi Everyone! I've been playing with drupal for a while and now I feel confident enough to try one on my own.
I hope this isn't a technical question. But, here goes...

What would be the best way to set up drupal to track user "activity".
This is a completely backend/administrative logging. The users never need to use this.

Hello,

I am new to drupal, so sorry for this dumb question, but i am crashing my head in order to figure out how i can do it.
I just try to have link/path for user account directly into a menu.

I did found 2 modules which could be able to do it :
* https://www.drupal.org/project/menu_token
* https://www.drupal.org/project/me

I'm looking at using domain masking (kinda like reverse proxy) to load up my Drupal 8 site for the sake of migration. It works well except in POST submissions because it automatically uses the default absolute URL instead of the reverse proxied URL.

I was able to get this to work by changing FormSubmitter::redirectForm, however that is literally hacking core. Obviously I'd love a hook but don't see how that's possible in Drupal 8 in this function. Here is the adjustment I made:

[SOLVED--See comment below.]

I'm installing Drupal 8.1.1 8.1.2 on a newly configured CentOS 7 server. FWIW, I have installed a lot of Drupal (though often not done much past that!) and fixed a lot of requirement errors but I haven't seen this one before and I'm baffled.

Here's the text:

Unicode library Error
Multibyte string input conversion in PHP is active and must be disabled. Check the php.ini mbstring.http_input setting. Please refer to the PHP mbstring documentation for more information.

I have just enabled glossary view and disabled after some time.Then I find this:

"The website encountered an unexpected error. Please try again later."

When I refresh the page, Seems it doesn't like that either and get the same error message.

The error log says:

mod_fcgid: stderr: Uncaught PHP Exception Symfony\\Component\\Routing\\Exception\\RouteNotFoundException: "Route "view.glossary.page_1" does not exist." at /home/drupal/public_html/core/lib/Drupal/Core/Routing/RouteProvider.php line 191.

Thanks in advance.

I've been following along with a couple of the online resources for theming in Drupal 8, and I've gotten as far as making a .info.yml and a .libraries.yml file. I've got the CSS working just fine on the test page I'm working with, but for some reason, none of the Javascript is getting onto the page. As far as I can tell, I've done everything I'm supposed to for it, and I haven't been able to find any online resources that help. Any ideas where I might have gone wrong?

Thanks!
