Hummingbird settings not saving

Trying to save a setting. I Cleared full cache when post/page is updated. It does not save. I’ve disabled all plugins besides WPMU Dev ones and tried to save but no change. Please check and help.

    Hello Barefruit!

    I’m sorry to hear you are facing this issue. I managed to establish the source of it, though.

    The error is caused by the fact that you are using an old version of WordPress (4.6.1, 2.5 years old, while current version is 5.1). Hummingbird tries to use a function that was introduced in WP 4.7, sanitize_textarea_field() and this causes the error to appear – it’s unavailabe in in the older version of WP you are using.

    The best solution, not only to make this error go away, but for security reasons is to update your WordPress to latest version.

    best regards,
