Unable to activate

[tickquest]

We have just purchased PDF stamper, we downloaded the zip files and installed it.

When we try to activate it using license key provided in the email, we receive the following error message.

Fatal error: Call to undefined function curl_init() in /…/public_html/research/wp-content/plugins/wp-pdf-stamper/wp_pdf_stamp1.php on line 0

Please advice.

Looks like your server do not have CURL library installed on your server.

Did you use the minimum requirement checker plugin for the PDF stamper before purchasing the plugin?

Minimum Requirements for the WP PDF Stamper Plugin

“CURL” is a very popular PHP library that is usually installed on every server. Please request your hosting company to install CURL and they should be able to do it easily (CURL is a free PHP library).

Thank you for the answer.

We have an alternative server that has CURL library installed, so PDF stamper is working now.
