problem issuing the certificate

Dear @mansurjon,

Thank you for the topic.

I want to mention, that you are currently using the old versions of both the Quiz Maker plugin and the PDF API addon.
The latest version of the plugin is the 8.7.4.

After updating the plugin to the latest version, you will be able to download the PDF API addon as well.

See the screenshot below:

Surely make a?DB backup?for your safety (you can use?UpdraftPlus) so as not to lose your created data.

As you are currently using the Pro version of the plugin, please contact us via this form for premium support. Our customer care specialists will always be happy to help you.
