0 votes

I have been using a  WordPress website on my local WAMP server but everytime I upload its database to live server, I get error

#1273 – Unknown collation: ‘utf8mb4_unicode_520_ci’

What can be done to avoid this ERROR? Any help would be appreciated!

This ERROR which is occurring will definitely be caused due to the versions running of the MySQL being different which are being run by the local and live server. To solve this ERROR, start with opening the SQL file in the text editor following which, please locate and replicate all utf8mb4_unicode_520_ci with utf8mb4_unicode_ci. Then Save and upload to a fresh mySql db. This should hopefully help you solve the ERROR.
