plugin crashing site

I have used this plugin for 6 years and it worked VERY WELL! However, it is now crashing my website https://vaep.info. When the plugin is active, the site will not load. As soon as I deactivate it, the website works perfectly. I am willing to pay for a plugin that does the same thing if one is available. Please advise on what is happening so we can continue to control the og.
