Side note and off topic: @themesumo Can you please avoid sending users to your site? There are many codex and 3rd party sites but sending the user to a post on your site can be misconstrued.
NOTE: I’m not accusing you of any ill will or bad behavior! Honest. Your support is very good but it’s important to avoid the appearance of sending users to your own site that way.
If a Codex article needs updating then please consider doing that and sending users that way instead.
i cleared all the cache also that i got from other topic.
