 * Hi there,
 * My debug log is full of this error:
 * [12-Jan-2026 16:02:44 UTC] PHP Warning: Undefined array key “_acf_screen” in /
   home/1423531.cloudwaysapps.com/rptarvczmb/public_html/wp-content/plugins/acf-
   to-custom-database-tables/includes/class-acfct-register-hooks.php on line 575
 * Is it just me and my setup or is it more common?
