Installing Magento 2.3.4 problem

 
 

I downloaded Magento 2.3.4 via FTP to my c Panel (blue-host) then I extract file and it worked.

Then I get the following error on my website:

Internal Server Error

The server encountered an internal error or configuration and was unable to complete your request.

Please contact the server administrator at [email protected]  to inform them of the time this error occurred, and the actions you performed just before this error.

More information about this error may be available in the server error log.

Additionally, a 500 Internal Server Error error was encountered while trying to use an Error Document to handle the request.

 

Kindly I need your support ASAP.
