I'm trying to import table rates , weight vs destination into Magento 2.2.3 but it comes up with the following error:
The file "C:/Windows/Temp/E:/xampp/tmp/php9B36.tmp" doesn't exist
I tried this solution below, but all it does is change the error message to:
The file "C:/Windows/Temp/C:/xampp/tmp/php10B39.tmp" doesn't exist
How can I fix it?
