I have been locked out of my dashboard with this message: Warning: include(/home/content/s/r/i/srini

I was trying to connect Jetpack to WP but forgot my login info. After the third try, it locked me out altogether with this message: Fatal error: Cannot redeclare grunion_media_button() (previously declared in /home/content/s/r/i/srinivas2010/html/wp-content/plugins/jetpack/modules/contact-form/admin.php:14) in /home/content/s/r/i/srinivas2010/html/wp-content/themes/care/functions/contact-form/grunion-contact-form.php on line 682

I tried re-naming the “grunion-contact-form.php” in FTP per the advice of someone in the forum. That only led to another error message. What can I do?
