I've installed the Universal theme with WP 4.4.2.
Installing the required plugins is no problem.
But when I'm installing the recommended plugin Revolution slider, I'm getting the following notification:
header information - headers already sent by (output started at /home/brondata.com/public_html/brondata.com/wp-content/plugins/themeple-shortcodes/register-shortcodes.php:849) in: /home/brondata.com/public_html/wp-includes/pluggable.php on line 1228
Consequence is that when making a page - like the homepage - and saving it, then the same notification appears and I'm unable to reach the admin panel and to login/out.
Could you help me with this? I want to set up a homepage with a slider. (installing the Layerslider is giving the same notification (if i remember correctly).
