How to configure SonicWall to use WAN X1 interface with a VLAN ID or Tag?

1 Assign a Virtual Interface on WAN X1 port and put the VLAN Tag number. In this example, we use 35 and IP assignment uses DHCP.

2  Go to “Failover & Load Balancing ” and Click configure

3 Click the arrow button and move X1:V35 to the top and click OK.

Now, SonicWall is going to use X1:V35 as the main port to connect WAN.

In my test, I have found out that if I leave the “enable load balancing”(Failover & Load Balancing) unchecked, it works too.

How to fix WordPress Admin Dashboard Not Display Correctly

The problem:

This problem might be caused by some faulty or outdated plugin .js that overrides something else when it is concatenated.

Open and edit the wp-config.php file (located on the root folder of the installation ). Make a backup of wp-config.php first.

add this define('CONCATENATE_SCRIPTS', false);

right before the line of: /* That's all, stop editing! Happy blogging. */

This will tell WordPress to load each script on it’s own instead of combining them.
