I got my website back in the air.
Downloaded the Customizr3.2.5 ZIP file to my local drive.
Decompress and only looked at the inc directory. It has all the missing files, including the init.php.
Using Filzilla FTP, I renamed the original inc directory on my website to inc.org
Then uploaded the complete inc directory from my local harddrive to my website.
Back in the air.
Thanks to Nikeo and the other forum members for the help.
Hope this will not happen again.
Cheers,
Richard
