• After activating this plugin I got an error: Fatal error: Call to undefined function wpcf7_add_form_tag() in …./wp-content/plugins/cf7-cost-calculator-price-calculation/backend/checkbox.php on line 9

    I see in the support forum someone has had this problem almost 2 months back and is still not answered/solved.

    Update: Feb-2018: I updated my wordpress to latest version and then also contact-forms-7. The plugin has been working fine since then!
