Fatal Error Memory Message When Trying to Edit Views.

I keep getting the following error when trying to edit my views…

Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 680993 bytes) in /home/welovecouponingo/public_html/wp-content/plugins/content-views-query-and-display-post-page/admin/includes/options.php on line 299

Can someone please help me fix this? Thanks in advance!
