WP Photo Seller – Fatal error under activation

[czdistagon]

activation – Fatal error: Call to undefined function filter_var() in /home/matvag/czdistagon.com/docs/wp-content/plugins/wp-photo-seller/models/WPSCommon.php on line 2916

p.s

WordPress 4.1.1

plug-ins from other vendors successfully activated.

I’m a novice )

That error occurs because either:

1. Your hosting provider forgot to include a flag, when they compiled PHP, and Photo Seller just happens to be the first plugin you’ve used that requires that functionality.

2. You’re not using PHP 5.2 or later.
