I get  “Forbidden

You don't have permission to access /test/index.php on this server.
Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request” error message when I tried to update dynamic object text file online.

After the website was uploaded, I was able test the pages and it worked, but there after, I couldn’t. It comes with the error message. What is the solution to this?

url: www.airtechng.com/test and want the client to be able to update the news and home page announcement sections. Regards.
