How to fix the "Allowed memory size Error" in localhost

The php memory resource can be increased in the php.ini located in the public_html or in localhost. The following steps will explain how to set the php.ini to allow a larger amount of memory use.

1. If you have access to the php.ini file,  open xampp\php\php.ini file and find memory_limit, then       set the memory_limit option to 512M 2. now open your project folder and you will find php.ini file set memory_limit option and place       512M there. 2. If you don't have access to it, you can try to set it in the .htaccess with: open your project              .htaccess and place this line     php_value memory_limit 512M; 3. now open your project admin folder you will find again php.ini file, set      memory_limit 512M; 3. If you change it on php.ini file don't forget restart the server after change the value. Your server have the memory_limit set to 64Mb and Open Cart need a little more. I hope this help you.
