An error has occurred while trying to update the license file | DirectAdmin

*** An error has occurred while trying to update the license file ***

Two possible causes

  1. License expired
  2. Missing part of Hostname SSL certificate.

Solution:

  1. Ensure your server is running an authentic copy of DirectAdmin at https://license.directadmin.com
  2. Install an SSL certificate for your hostname using LetsEncrypt 
    /usr/local/directadmin/scripts/letsencrypt.sh request_single your.hostname.com 4096

That’s it.

You can also redirect non-SSL request to a specific URL. Just do it.

/usr/local/directadmin/directadmin set ssl_redirect_host your.hostname.com
service directadmin restart

How to enable exec()

To enable exec() function, you have to modify php settings using a php.ini file.

  1. Open php.ini file and search for disable_functions exec
  2. Delete “exec” from disable_functions 
    disable_functions = "show_source,system, shell_exec,exec"
  3. Save the changes and reboot server.

That’s it!

Caution:

When a PHP script is hacked, the hacker can use the exec function to cause further issues. However, exec function itself is not dangerous.

Note:

OJS needs exec function for extracting text from PDFs for search indexing etc.
