Question 1

How does the DNS Work  and How To Edit DNS Records with cPanel

Accepted Answer

How Can You Manage DNS of Your Domain In cPanel

It is important to know working of DNS First before proceeding.When you register for a domain, the domain registrar provide you a control panel named Domain control panel (it is different from cPanel or any other web hosting control panels).

Here you can specify the name servers of the domain,you can renew the domain name, changes in contact information of the domain and many more. These name servers designated in the domain control panel are the authentic name servers of the domain. In these authoritative name servers, it needs to be a zone file in which the DNS records (like NS,A, CNAME, TXT records ) are added.

For perfect name resolution the NS records should be same as the name servers entered in the domain control panel

Users using our name servers, can easily alter the DNS zone file or DNS records in cPanel. Those who are using exterior or any other third party name servers (eg: CloudFlare services), you need to update the DNS records or zone file there in their DNS management area.

Question 5

I am getting an 500 error on my site, what should I do?

Accepted Answer

If you are getting a 500 Internal Server Error on your site, as a rule, this is because of a PHP error/coding error or corrupted .htaccess file.

To analyze PHP errors on your site, you can check (either by means of the File Manager in cPanel, or through FTP/SSH) for records named 'error_log' under your public_html or respective folder of your files.

https://media.cyberin.in/file/docs/500error.png (500error)

The folder of the document will by and large be the place the code is executed - for instance, on the off chance that you have encountered a 500 error on the landing page/file of your site, the error_log record will be under the public_html folder.

Assuming, as it may, you are just getting the 500 error in a specific catalog, (for example, wp-administrator for instance) at that point the error_log record will be situated in the public_html/wp-administrator directory.
