While trying to update the plugin it throws an SSL certificate error:
cURL error 60: SSL certificate problem: certificate has expired
Try deactivating your license key and reactivating it.
I tried it but I can’t either deactivate the license. Same error occurring on every website.
I just tried doing an update on a site and it worked as expected.
I think this has something to do with where the sites are hosted. Are all the sites you are testing hosted in the same place? Honestly I don’t know, but it’s working for me and the only difference I can see is that you’re likely not hosting where I’m hosting.
This is sometimes on certain hosts.
You can add the following line temporarily to your functions.php:
add_filter( 'https_ssl_verify', '__return_false' );
As a long fix, contact your hoster to update his ca bundles.
