Installed HTTP compression plugin, now my website doesnt work, help please!!

Hello, just about 10 minutes ago i was looking for plugins to make my website fast and i found this one

https://www.ads-software.com/extend/plugins/wp-http-compression/installation/

So i downloaded it and then uploaded it from my WP cpanel.

After i check my home page at https://www.bigbrownmarketing.com and it does not show up anymore?

And now my wp cpanel looks like the picture below

Please i spent countless hours writing and making the website, and i have no knowledge of coding so imagine how hard it would be to do it over again. All i did was install one plugin and it stopped working so the problem cant be that bad right? It might be really simple, but i do not know.

Thank you for all that help!
