Hello guys. Currently we see and error when user tries to login to our website. It need to try to login 2 times before it can access website, it doesnt login from first try on login sidebar. Currently we also use wp rocket, maybe this affect the functionality?
Yes, in most cases the issue is because of the cache plugins. Please deactivate all the cache plugins from the site and server then check back the site, I am sure your issue will be solved.
