ERR_CONNECTION_RESET

After an update, my website goes weird and when I check the “console” a lot of ERR_CONNECTION_RESET errors.

Here is the image https://s30.postimg.org/g7nxclmv5/error.jpg

I can’t clear the cache because nothing happens when I click the clear cache button (wordfence cache feature and already reported it).

Help me please.

Thanks in advance!
