URGENT - Page does not load due to unknown bug

My site was working fine until I made a change somewhere (which I don’t remember) and now one of the pages isn’t loading at all. It does not go past the pre-loader balls and it is the only page with such bug.

http://x4h.388.myftpupload.com - this is the site

http://x4h.388.myftpupload.com/cnc-machining/ - this is the page that does not load. It is the only one.

Thanks very much for your help.

Hello there,

Special content in added with page builder widget might be the source of this issue. I guess Grafity Form. To verify it yourself, edit that page, and try removing the Grafity Form. Then reload that page.

My page is not loading. An update to a sydney toolbox and site won’t load.
I just don’t understand this.
This is the second or third time it’s crashed after a suggested update.

HELP!
Here is the message I get when I attempt to load our page
Parse error: syntax error, unexpected ‘[’ in /home/nitro/public_html/wp-content/plugins/sydney-toolbox/sydney-toolbox.php on line 100
