crashed my site

after installation of this “gallery plugin” i’ve got critical error
fatal error: call to undefined function awesome_gallery_shortcode() in /home/dogart/public_html/wp-content/plugins/photo-gallery-awesome-responsive-image-gallery/main-function.php on line 29
which completely brake down my website!!!! i wasn’t able to uninstall this stuff!!!
only thing that i receive after installation of this “gallery plugin” – alot of problems and wasted time be aware

to fix this problem i was forced to hire person who helped me out with recovery of my website after this crash this is time and money wasting. don’t be catched like i did
