Okay thanks but I couldn’t wait so I just had to brute force it on my end and manually re-apply all the theme customizations on our GoDaddy hosting site. Won’t be able to provide you with feedback on the changes here.
I am also experiencing this problem. Using your plugin under WP 6.1.1 on a Synology NAS, export seems to complete successfully. But when I then try to import resulting DAT file under WP 6.6.2 via GoDaddy, I get a “File Type Not Allowed” error.
