How to Solve the Errors 401, 403, 404, and 500 on the Web Page?

After the site is ready, users upload the files to the server via FTP. However the real problem begins after that. You say that your files are complete, but some of your files can be overlooked and if the site's main file is not included in the management files or because of other reasons, your site gives errors in different ways.



401 Unauthorized Error and Resolution

Before you encounter the 401 error message, the web browser you mostly use can open a dialog window and ask for a user name and password. If you don't know this username and password, you'll see this error on the page when you want to close pop-up.

To fix this error, you only need to know the login information of the site. You can connect via the screen by logging in with the membership information. However, if there is an error again, a more detailed action can be taken by contacting the site owners.



403 Forbidden Error and Resolution

This error is usually encountered on systems that use Apache as a web server. The main reason of this error is that there is no right to work in the folder. The authority to execute on apache services on hosting companies is automatically defined.



404 Not Found Error and Resolution

The reason of this error is that your Web site's homepage or any page is not on the server. If you get 404 error when you try to open your homepage, there is an access problem in your server due to lack of index.php, default.php, homepage.php pages.

If you transfer your missing file to your server, the problem will be eliminated.



500 Internal Server Error and Resolution

The 500 error is generally a server-driven error. It means something has gone wrong on the website’s server. In order to get rid of the Http error 500, you must first determine the cause of the error. To do so, click the admin panel of your site.

The most common reasons of the http error 500 are as follows:

- There may be errors in the site software due to coding,

- The Google servers on the server may not respond,

- Your site's .htaccess file may be corrupted and others.



The best way to solve this problem is to turn over the process to your service provider after optimizing your site's configuration.
