Website breaks after migrating to live server

My website works fine on local but once i upload to a live server it returns “ a critical error occurred “ i’ve tried wp-all-in-one , duplicator , updraft but nothing seems to work.
I’ve tried exporting the data base but I’m unable to import it

Hi @Ayhameed! Usually, this indicates a critical error with a plugin or theme. Are you able to look at any error logging to see if anything is popping up? What host are you trying to get the site uploaded to?

I’m trying to upload to namecheap,
it’s returning "critical error " no error log

I’m sorry for the trouble you’re having. Your best bet might be to contact Namecheap and see if they are able to manually migrate the files for you or see on their end what might be causing the hang-up: https://www.namecheap.com/help-center/live-chat?loc=/general/
