Once a month I've been saving iframe details in textarea. Its been working up until this month / today when I went to add a new iframe details and it wont save? It will save just text but doesnt seem to save html anymore?

Thank you in advance for your time and input.

Hi, since the version 5.1 of Meta Box, we have added a sanitization for all inputs to improve the security. Textarea by default will have the wp_kses_post sanitize callback, which will strips all iframe, script and style.

To bypass the sanitization to make it accept iframe, please add this setting to the field:

'sanitize_callback' => 'none'

See more in this docs: https://docs.metabox.io/sanitization/#bypass-the-sanitization
