I got solution. I just removed ‘/’ the end of this path /home/server_name/public_html/invoice
That’s same as this ‘character only on line 93.
Maybe commenting here by pasting code changed to '.
I have checked wp-config.php file and it is like this on line 93:
/* Upload any file format */
define(‘ALLOW_UNFILTERED_UPLOADS’, true);
This issue solved by updating wordpress to latest version.
I want to suggest you to add these below features,
1. Add order status option
2. Add Order history at POS interface
3. Add Payment option
Thanks of the great plugin.
