Some issues in 3.15

@arnan,

I found some issues with a version 3.15

1. W3TC detecting error is showing even if W3TC is turned on.
There is a mistake in line 697 of adrotate-output.php
You have an extra slash before ‘w3-total-cache/w3-total-cache.php’

2. You forgot to define $output.
The same file. Function adrotate_custom_javascript. If $output_js is not isset then $output will not be defined.

3. Error message without logo.
The same file. Line 733. You have a wrong way to logo. In the images folder only ‘logo-60×60.png’ exists. But the logo is linked to ‘adrotate-logo-60×60.png’

Thank you for your work.

Regards, Talgat
