Background of the issue:
I am trying to update WPML, but after doing so, I encountered an error message stating that my site doesn't meet WPML's minimum requirements. I checked with my developers and hosting teams, and they confirmed that the WordPress REST API is working and reachable. They used the command wp eval 'print_r( rest_url() );' and curl to verify this, although curl returned a 401 error, which they said is expected due to authentication requirements. The issue can be seen at hidden link.
Symptoms:
After updating WPML, I received an error message: 'Your site doesn't meet WPML's minimum requirements.' The REST API endpoint is reachable, but WPML still reports an issue.
Questions:
Why does WPML report that my site doesn't meet the minimum requirements when the REST API is reachable?
What steps should I take to resolve the error message after updating WPML?
Looking at the debug information that you provided, I see that the Rest API is enabled on your site. Have you tried closing this message?
However, if you check the site using the following URL hidden link, as you mentioned, there is a 401 error saying "Sorry, you do not have permission to make REST API requests." Usually, such requests are accessible.
Your message: "However, if you check the site using the following URL hidden link, as you mentioned, there is a 401 error saying "Sorry, you do not have permission to make REST API requests."
Their reply:This is expected as no API token is provided when you visit that enpoint via the web browser
So the 401 error says that you don't have permission because you're not authenticated with a token
I need to request temporary access (wp-admin and FTP) to your site—preferably to a test site where the problem has been replicated, if possible—in order to be of better help.
