chrisarella on "[Plugin: Tesla Login Customizer] Plugin could not be activated because it triggered a fatal error"

Hi. I've been a Lifetime Tesla Themes member for a while now and love your themes. I just installed your login customizer on one of my sites for the first time and when I tried to activate it I get the following error:

Plugin could not be activated because it triggered a fatal error

Parse error: syntax error, unexpected T_STRING, expecting T_CONSTANT_ENCAPSED_STRING or '(' in /home/content/c/h/r/chrisarella/html/halloween-wedding/wp-content/plugins/tesla-login-customizer/tt_login.php on line 16

Any ideas what is causing this?

As an aside, that path looks strange for a plugin to reside. Is that right?

https://wordpress.org/plugins/tesla-login-customizer/

To make sure this wasn't a fluke, I installed in on another site and got the same error:

Parse error: syntax error, unexpected T_STRING, expecting T_CONSTANT_ENCAPSED_STRING or '(' in /home/content/c/h/r/chrisarella/html/cobra/wp-content/plugins/tesla-login-customizer/tt_login.php on line 16

All of my sites are running WordPress 4.5.2.
