  • Hello @almendron ,
    Thank you for reporting this, we’ve seen this issue with GoDaddy hosting where WordPress installations there have mixed collations of database. They don’t respect the default collations and use their own set collations while creating default tables ( in this case utf8mb4_unicode_ci ) and when creating the custom tables they use WP’s collation ( in this case utf8mb4_unicode_520_ci ) which is causing this error.
    We have tried to fix this from the plugin but unfortunately we couldn’t.
    Furthermore, this may also be causing errors with other plugins that rely on the post table or make changes to it.
    You’ll probably have to check in with your hosting about this and see if they could use the standard charset for this?

    Best regards,
    Biplav.
