Apologies for the delay in response .Support remains off on Sundays .
It looks like you did not checked the link that I shared above . Its good that you have increased the memory limiton server but in wordpress you can control memory limit with wp-config.php file also .
Please follow this link to increase your php memory limit :
https://docs.woocommerce.com/document/increasing-the-wordpress-memory-limit/
if already tried still getting same limit then please share your site url , admin credentials and a valid ftp credentials to check this out at your end .
