 * Would it be too much asking for your input on how to solve this error preventing
   to start the installation?
    [PHP ERR][FATAL] MSG:[snuffleupagus][disabled_function]
   Aborted execution on call of the function ‘function_exists’, because its argument‘
   $function_name’ content (shell_exec) matched a rule [CODE:1|FILE:/home/sdq/public_html/

 * Hey [@shimodabt](https://wordpress.org/support/users/shimodabt/)
 * Thanks for the feedback! It’s possible your host does not support shell_exec.
   In this case, you will want to switch to the following modes:
 * Settings > Packages Tab
    > SQL Script > PHP Mode > Archive Engine > DupArchive
 * Also, there are a few items in the FAQ that may provide a solution to this issue,
   this one may get you going.
 *  – What’s the difference between “Shell Zip”, “ZipArchive” and “DupArchive” Engines?

 * Hi [@corylamleorg](https://wordpress.org/support/users/corylamleorg/). Thanks
   for the quick feedback! After few attempts of reinstalling WordPress using CPANEL,
   I finally was able to restore the backup.
