Hi All,
Feedback: Currently the CloudFlare ipv6 was not function well, please ensure you ipv4 work. After I updated (in wp-content/w3tc-config/master.php) the CloudFlare new IPs, CloudFlare API request was successful.
Herewith the new ipv4 and ipv6 lists for your review and checking.
Pls inform that my 2 sites IPs list was totally different (weird). You can review you wp-content/w3tc-config/master.php (not in the wp-content/cache/config/master.php).
Please backup/keep a copy your old IPs lists for safety purposes
MY IS WORK NOW.
