Experiencing the same error with UpdraftPlus Version: 1.15.3 .
Where is the resolution, if this error has been resolved?
thank you.
this worked for me.
thanks.
1. Open database, open wp_options table .. look for ‘db_version’.
2. Make note of the number in the option_value.
3. Open your version.php file inside of the /wp-includes folder and find $wp_db_version.
4. keep record of the current value and then Update $wp_db_version with the number to match the number that you just found in your database.
