Issue #1: New xampp security concept: Access Forbidden Error 403 - Windows 7 - phpMyAdmin
Solution:
1. Open Xampp
2. From Apache module >  Config > Apache (httpd-xampp.conf)
3. Find and change section below:
<Directory "E:/Servers/Xampp/phpMyAdmin">
        AllowOverride AuthConfig
        Require local
        ErrorDocument 403 /error/XAMPP_FORBIDDEN.html.var
    </Directory>

Change:
<Directory "E:/Servers/Xampp/phpMyAdmin">
        AllowOverride AuthConfig
        Require all granted
        ErrorDocument 403 /error/XAMPP_FORBIDDEN.html.var
    </Directory>

Now, we can access the MySQL Admin from other PC on Local Network.

3:05:30 PM  [Apache]     Apache WILL NOT start without the configured ports free!
3:05:30 PM  [Apache]     You need to uninstall/disable/reconfigure the blocking application
3:05:30 PM  [Apache]     or reconfigure Apache and the Control Panel to listen on a different port
3:05:30 PM  [Apache]     Attempting to start Apache app...
3:05:31 PM  [Apache]     Status change detected: running
3:05:43 PM  [Apache]     Status change detected: stopped
3:05:43 PM  [Apache]     Error: Apache shutdown unexpectedly.
3:05:43 PM  [Apache]     This may be due to a blocked port, missing dependencies,
3:05:43 PM  [Apache]     improper privileges, a crash, or a shutdown by another method.
3:05:43 PM  [Apache]     Press the Logs button to view error logs and check

Root cause: Port 443 is duplicated.
Resolved:
Edit port 443 & 80
1. xampp > apache > conf > extra > httpd-ssl.conf
Find 443 and change other port which you want.
Ex: 443 -> 444

2. xampp > aoache > conf > httpd.conf
Find 80 and change other port which you want.
Ex: 80 -> 8080
