Cannot see my website after uploading file via FTP

I had FTP files to htdocs folder but I cannot see my website at the URL www.intellwares.com. Can this forum admin or someone else guide me?

http://www.intellwares.com seems to be working fine from here. If you created the account or added the domain only in the last few days, note that due to DNS caching it can take up to 72 hours for your domain name to start working everywhere.

I do not need to change htaccess document correct? I cannot find site-available folder as in apache server. I put ns1-5.byet.org in my domain hosting’s nameserver in the beginning but still cannot see anything from you.

The sites-available server is part of an Apache installation on Debian or Ubuntu. But InfinityFree provides shared hosting, meaning you don’t get access to the main server configuration (data for all accounts on the server is stored there, not just your own websites) and we use CentOS (which has a different folder setup anyways).

I put ns1-5.byet.org in my domain hosting’s nameserver in the beginning but still cannot see anything from you.

When did you do that? Note that it can take up to 72 hours for you to see the DNS change due to caching by your computer or your internet provider.

I can see my site up. But how do I upload a 404 error or any error page to the website? When I submit the form, it shows a 404 error page from infinityfree. It is suppose to send an email to [email protected] What is wrong? I

You can customize your error pages either through the Error Pages in the control panel or by adding ErrorDocument rules to your .htaccess file.

What about the sending email problem? There is no email sent.

I tried this page blank white page / 500 error | Hosting KnowledgeBase instructions

and input the link php_value display_errors in htaccess file which prompt me to select file. I selected a error html page. but I still fails.

Well, if you get a 404 error the form URL is likely incorrect, so the form input may not even get processed.

Regarding email issues, please see this FAQ article: https://infinityfree.net/support/php-mail

I did not host email with you. Does php-mail work?

Please see the article I linked before. As the URL implies, it’s about PHP mail.
