Solution for Fatal Error: Allowed Memory Size Exhausted

This example gives you the solution for Fatal Error allowed Memory Size Exhausted which causes to stop application running all of sudden. I have purchased the GOOD DOMAIN Hosting w/ Cpanel and tried to install various WordPress plugins to make my website more flexible to users with  design and content

However I got this error when I tried to activate the plugins:

Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 12288 bytes) in /home/pangko/public_html/wp-admin/includes/menu.php on line 65

Sometimes the error will be like below:

Fatal error:  Cannot use output buffering in output buffering display handlers in Unknown on line 0

I did my research which lead me to changing my wp-config.php by adding this line at the bottom before change limit comment:

define( 'WP_MEMORY_LIMIT', '256M' );

However it still doesn’t work, I am helpless when i see this error in my WordPress admin panel.
