`define (‘WP_MEMORY_LIMIT’, ’64M’); adding this to wp-config can solve my problem ?`

This is a non question the response to which always has to be ‘You tell us’! try it does it fix the issue? it’s a simple test.

if it doesn’t then your host may not permit individual sites to alter PHP at site level ( very sensible on shared hosting) in which case you may need to speak to tech support and ask that the memory limit is increased or whether it can be.
