Please download v1.0.24 version from My Account menu of webshoplogic.com, and update your plugin (just unzip and copy it into your plugins directory).
Then set the „Show License Activation Detailed Technical Information” checkbox in Settings / WooCommerce Custom Tabs menu (this is a new option in 1.0.24 version).
After this, please try again the license activation.
Right after the activation, you will find an „Activation technical information” section at the bottom of the activation page. Please copy the displayed information into an e-mail and send to info@webshoplogic.com.
Thank you in advance.
