#1273 – Unknown collation: ‘utf8mb4_unicode_520_ci’

Question

I have a WordPress website on my local WAMP server. But when I upload its database to live server, I get error

#1273 – Unknown collation: ‘         


        

Answer 1

In my case I substitute it with utf8_general_ci with sed like this:

sed -i 's/utf8_0900_ai_ci/utf8_general_ci/g' MY_DB.sql 
sed -i 's/utf8mb4_unicode_520_ci/utf8_general_ci/g' MY_DB.sql 

After that, I can import it without any issue.
