Method 1: Using an FTP
Using an FTP client like FileZilla is one way to change the .htaccess or wp-config.php file. Before starting either of the steps below, make sure FileZilla is linked to the FTP account for your website.
- Find the .htaccess file in the root directory or public_html folder of the website.
- To open the file in the text editor, right-click on it and select View/Edit.

- Search the line:
code:
# END WordPress
- Under that line, write the given code:
php_value memory_limit 256M

- After saving the modifications, close the editor.
- When FileZilla prompts to upload the modified file, click Yes, then refresh the site.
Method 2: Using a File Manager
Increase the WordPress memory limit by editing the .htaccess or wp-config.php file using the built-in File Manager of your hosting account.
1. Log in to Your Web Hosting Control Panel :
- Go to your hosting account (e.g., cPanel, Plesk, DirectAdmin).
- Open the File Manager.

2. Locate the wp-config.php File :
- Navigate to your WordPress installation directory (usually public_html or a subfolder like public_html/yourdomain.com).
- Look for the file named wp-config.php.

3. Edit the wp-config.php File :
- Right-click on wp-config.php → choose Edit or Code Editor.
- Scroll down to find the line:
php:
/* That's all, stop editing! Happy publishing. */
- Just above this line, add the following code:
php:
define('WP_MEMORY_LIMIT', '256M');
- You can replace 256M with any other value depending on your hosting plan, e.g. 128M, 512M, 1024M, 2048M etc.
4. Save the Changes :
- Click Save Changes or Save File in the editor.
