See suphp is the default handler on the server

Run:

/usr/local/cpanel/bin/rebuild\_phpconf --current

Sample output:

Create entry in the .htaccess
- Change to the website docroot directory:
```
cd /home/username/public\_html/  
```
- Open a text editor to modify the .htaccess file:
```
nano /home/username/public\_html/.htaccess  
```
- Add the following to this file:
```
<IfModule mod_suphp.c>  

suPHP_ConfigPath /home/USERNAME/public_html/  

</IfModule>  
```
  ⚠️ MAKE SURE TO REPLACE THE USERNAME WITH THE ACCOUNT USERNAME

Copy php.ini into public_html folder unless one already exists
- If php.ini does NOT exist
  - Copy the global PHP configuration to website docroot so that custom PHP settings can be applied to the descending content:
    cp /usr/lib/php.ini /home/username/public\_html/
  - Open a text editor:
    nano php.ini
  - Modify the line for memory limit:
    memory_limit = 64M
- If php.ini DOES exist:
  - Open a text editor:
    nano php.ini
  - Modify the line for memory limit:
    memory_limit = 64M

Wordpress has additional memory restrictions that will need to be edited.

Open a text editor to edit the file shown below:
```
nano wp-includes/default-constants.php  
```

Modify the lines that correllate to the information below:

// set memory limits  

if ( !defined('WP_MEMORY_LIMIT') ) {  
    if( is_multisite() ) {  
        define('WP_MEMORY_LIMIT', '64M');   <------Change value to reflect value from php.ini  
        } 
    else {  
        define('WP_MEMORY_LIMIT', '64M');   <------Change value to reflect value from php.ini  
    }
