security check failed ! when wanting to see students enrolled in course

[dmac]

Hi, Whenever I am logged in as admin and want to see the students enrolled in the course, I only can see the first couple of students and whenever I click on the button at the bottom right to go to the second page of students, I get to see the message 'security check failed !' As far as I know we don't see this message on other parts of the site but I cannot 100% guarantee it. We are using the WP Rocket plugin for caching and the caching life span has been set to 10 hours. I am wondering if this is too much since the theme might have customized the nonce lifespan. Is there a way to figure out the nonce lifespan? Thank you!

Hi Mk,   Thank you for your response! After WP Rocket got back to me I lowered the caching life span to 5 hours. Now the issue I mentioned above is resolved. User Caching had also been activated, which could cause the same problem. I will monitor if the error will appear again in the future and what effect disabling 'User Cache' will have. If I still encounter the same error in the future after taking the steps mentioned above, I will provide you with our login details.

Hey @dmac, Great Job, Actually, this issue always comes due to caching. There are many users who faced the same issue due to caching. hopefully, it would not occur again.
