 * Hi [@damianhayes1](https://wordpress.org/support/users/damianhayes1/) ,
 * Thanks for reaching out to Duplicator support.
 * I understand that you are not able to install your backup and got the below error:
   [
   PHP ERR][FATAL] MSG:Uncaught TypeError: decoct(): Argument #1 ($num) must be 
   of type int, string given in /homepages/34/d961141668/htdocs/cleopettitt.com/
   installer.php:607
 * We have encountered similar issues, and this happens because you’re trying to
   import an old package created with a PHP version less than 8.
 * To fix this issue, you need to downgrade your destination website’s PHP version
   to 7.4 and retry the installation.
 * I hope this helps.
 * Thanks!
