Hello,
what I do is: open the following file:
/contact-form-7/includes/controller.php
Comment out the following lines like this:
###?Commented out to resolve "refill" extra loading time
#if ( defined( 'WP_CACHE' ) && WP_CACHE ) {
# $wpcf7['cached'] = 1;
#}
You have to manually comment them out every time you update the plugin but that’s the only way I could successfully solve the issue.
In my opinion, the developer of the plugin could add an option to deactivate the “refill”, should you wish to…
If anyone found a better working solution, please share it with the world ??
I hope this helps your needs, at least for now.
Best regards
