I have a site that use ACF and it works perfectly at localhost but when moving to a hosted server i got “Failed to load resource: the server responded with a status of 500 (Internal Server Error)”. I have tried to inactivate all other plugins so i think its ACF that goes wrong when moving. Anyone have an idea of whats wrong?
Did you changed the database creditials to the web hosting envoirement?
Otherwise write the error log in here (https://codex.wordpress.org/Debugging_in_WordPress).
