Solution:
Just create the file named php.ini under wp-admin folder and add the below lines,
<? phpinfo(); ?> memory_limit = 64M
save changes and close the file.
Refresh the page. Hope you will not get the error now.
Note:
1. Be sure that you have not added any other lines in any other files.
2. If you still getting the same problem, then try changing the value to 128M.
