Fatal error

I installed your plugin on 3 of my sites and they all now show the following message when going on to wp-admin:

Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 262123 bytes) in /home/meatbag/public_html/carrot.marketing/wp-content/plugins/wpmudev-updates/includes/class-wpmudev-dashboard-site.php on line 1061

I am now blocked out of my site, please help!
