tolong gan, mohon bantuanya,,,web saya —–
Looks like the problem is with different subdomains in “WordPress Address” and “Site Address” (i.e. http://www.example.com and http://example.com ). The cookies are set for the subdomain listed in WordPress Address, the wp-admin also runs from this subdomain, whereas the live preview uses the Site Address => the cookies does not match => session expired.
Thus make sure that WordPress Address and Site Address URLs include the same subdomain.
Worked like a charm! Thank you!
