To disable the plugin you can log into cPanel or into the installation folder via FTP and rename or remove the plugin folder in /wp-content/plugins/ - Once you've done this you should be able to login to the dashboard without any issues.

There is possibly a conflict between the current theme and the Contact Form 7 plugin that you are trying to use. Maybe try an alternative contact form plugin like Gravity Forms and see if you have the same problem.

wpcf7_add_shortcode is deprecated since Contact Form 7 version 4.6! Use wpcf7_add_form_tag instead:

Can you please update your plugin?

Also deprecated :

WPCF7_Shortcode

WPCF7_ShortcodeManager

wpcf7_add_shortcode()

wpcf7_scan_shortcode()
