Plugin bug

Hi. I have disabled thirstyaffiliates plugin and remove it cause i didnt need it anymore. But now my site crashed (https://www.drinko.com.br) But the bizarre thing is when i hit ctrl f5, it goes well. The same thing if i’m logged in the wp-admin.

Does anyone knows what is going wrong? I have reinstalled the plugin but the problem still happening.

Any ideas?

Thanks
