Unbounce Pages – page is blank after plugin installation

After installing the plugin (Unbounce Version 1.0.16) and clicking on the new “Unbounce Pages” menu item on the left all I was shown was a blank page.

We self-host on our own VPS running Ubuntu 14.04.

I thought at first there was some sort of javascript compatibility error, but finally tracked down the problem after turning on debug mode in wp-config.

The “Unbounce Pages” showed the following error after turning on debug mode:
“Fatal error: Call to undefined function curl_init()”

I didn’t see Curl anywhere in the plugin installation requirements..
Or any mention of it on the offical site’s documentation, which just mentions:
Self hosted WordPress site, Access to your site admin, PHP version 5.3 or higher. (https://documentation.unbounce.com/hc/en-us/articles/205346520)

You should probably list “php5-curl” as a requirement or check for the existence of the curl function in php and display an error stating it needs to be installed.

I was able to get things working by installing php5-curl and then restarting apache:

# sudo apt-get install php5-curl
# sudo service apache2 restart

Hopefully this helps someone else.
