/opt/homebrew/etc/php/8.0/php.ini – or whichever PHP version you’re running – find and increase
memory_limit to 512M or 1024M or whatever you need to debug.
memory_limit line is commented out – i.e. has a prefix of
; – make sure to remove it).
You may also need to add the following line to your
wp-config.php (matching whatever value you set in
define( 'WP_MEMORY_LIMIT', '1024M' );
Finally, you should probably run
valet restart from the command line.
