I’m Japanese.
I don’t speak English, so I use translation software.
I’m sorry if I’m using strange language.
I’m troubled with this problem too.
I dealt with it by using “WP Rollback” to roll back the version of “WordPress Popular Posts”.
Because I didn’t understand the way to deal with it written here.
Please let me know.
Will this fix be included in a future version?
I would prefer that the problem be fixed by just upgrading without adding or editing any code.
