How to increase the memory in your WordPress website without FTP access, or any real full-stack skills.
Step 1. Login to your WordPress website
Step 2. Go to Plugins, download a File Manager Plugin, Install + Activate the plugin.
Step 3. Select the activated File Manager Plugin in the sidebar menu
Step 4. Add
define( 'WP_MEMORY_LIMIT', '64M' );
To your wp-config.php file, press save. Adjust the MB number as needed.
Step 5. Deactivate + Delete the File Manager Plugin. I personally don't like to leave it activated or installed as it can create a security risk.
