Hi Shay here, willing to assist.
can I get mor info on this error like
what's your Docker file look like? And what base image are you building from?
Also, are you running PHP-FPM or just straight mod_php? And do you have any custom Apache configs you're copying in, or is it all stock?
If you've got a railway.json or a custom start command set up in Railway, drop that here too. I need to see exactly what's getting loaded so we can kill the duplicate MPM

your log says AH00534: apache2: Configuration error: More than one MPM loaded and thats the whole problem, apache has two MPM modules enabled at once (like prefork AND event) and it refuses to start. you can only have one. if youre on a php image with mod_php you need prefork; if youre using php-fpm you usually want event. disable the extra one, e.g. a2dismod mpm_event (or mpm_prefork, whichever you dont want) in your dockerfile before starting apache. if you didnt set this up yourself its coming from your base image stacking modules, so check what your FROM image enables.
