WP Super cache & Contact form 7

I have my wordpress site installed from localhost and moved to the prod server. My contact form submissions don’t work on the server but it works on my localhost. I had WP Super Cache and Contact Form 7 and I even tried deleting the super cache plugin but it doesn’t work. Though I get the <!– WP Super Cache is installed but broken. The path to wp-cache-phase1.php in wp-content/advanced-cache.php must be fixed! –> error at the bottom of every page except front page (appearing even after deleting the plugin, that’s so weird). I have googled this and I’m exhausted. Any help is really appreciated guys..

Thanks in advance.
