Hi Aakash,
i am not sure how this is working, but after the update of shortcoder the wordpress-cache AND the WP-Rocket Cache is cleared everytime a page is visited.
I think the WP-Rocke cache is in dependancy with the WordPress cache (everytime WP-Cache is cleared, WP-Rocket does also).
So maybe it is a problem with shortcode and the wordpress cache. If i rollback to the previous version of shortcoder everything is fine.
i hope this helps.
all the best,
Lars
