At least for me, your website is working fine.
The only problem I experienced was with the website loading speed.
Here is a message from 000Webhost:
"We are having a network problems. Unfortunately, we're experiencing some networking issues that are affecting our web and mysql servers. If your site is suddenly not loading or can't connect to the database, it's most likely related."
"We're looking into this and will be posting updates if this network problem cannot be fixed in next 60 minutes. Please do not submit and tickets about this issue and do not increase our work load as we are fully dedicated in resolving this network problem. We thank you for your patience and understanding."
Have a good night!
