Product License page on backend is blank

[maurice.meyer]

When I open the “Product License” page on my backend to activate with my license key, I can enter it in the form and press “Activate”, it reloads the page, which is then blank.

I suspected this to be a PHP error which my Apache error log could confirm. The following error is occuring:

[Wed May 21 00:00:00 2014] [error] [client xxx.xxx.xxx.xxx] PHP Fatal error: Call to undefined function curl_init() in [here is the absolute path]/wp-content/plugins/wp-photo-seller/admin/includes/wps-lic-includes.php on line 49

To eradicate all possible error sources, I disabled all other plugins and reinstalled WP Photo Seller. The error still occurs.

After this, I checked the admin.php file in wp-admin and searched for the function “curl_init()”, which does indeed – as PHP claims – not exist.

If you need more data to work on this issue, I will happily provide it.

Did you install the cURL libraries, when setting up Apache?

You can ask your hosting provider to install the cURL library on your site (usually it is installed by default 99.9% of the time).

Thank you very much, that was the problem.

I haven’t had installed the libraries.
