Hello Mahmoud!
I think you forgot to add in the download files the SQL file that requires the script and that needs to be imported into the MySQL base created. XD - No problem, I bought this script directly in CODECANYON and attached the missing SQL file.
Also, the documentation, since your files do not have it. XD
Something I forgot to comment, I checked your files, and they don't include the extra plugins of the extended version of this SCRIPT. It is important for users to know that the version of files you are attaching is only the standard license version. So these extensions won't have it:
Custom domain for stores (no included)
