Since updating to the newest version of X, whenever anyone attempts to save a change this error occurs:
Failed to save E_ERROR: Uncaught ArgumentCountError: Too few arguments to function wp_get_footnotes_from_revision(), 2 passed in /home/ocwcog/public_html/wp-includes/class-wp-hook.php on line 324 and exactly 3 expected in /home/ocwcog/public_html/wp-includes/blocks/footnotes.php:139
I’ve delete the theme, and cornerstone and verified the files are gone, then reinstalled the theme and Cornerstone per the instructions.
