Raise the memory limit in WordPress
You can do this in 2 places. The php.ini file and in the wp-config.php file.
Adding Memory Limit in php.ini
To avoid error messages from different programs regarding memory limit. Why not increase the memory limit?
Set the value in php.ini
There are two php.ini files
Make sure that you edit the right one for Apache.
This is th one for command line. Do not edit this.
sudo nano /etc/php/7.0/cli/php.iniThis is the one used by WordPress
sudo nano /etc/php/7.0/apache2/php.ini
Ctrl+W to find in Nano editor:
memory_limit = 128M
post_max_size = 64M
upload_max_filesize = 64M
Change the memory value to 256M or whatever you like.
64M or 32M is an alternative if you are short on RAM on your 1 GB server.
Modify the max file size to your desire
Running only one website on a 1 GB server or there is more than 1 GB RAM on the VPS. Then sentence could read:
memory_limit = 256M
Save and exit the file in Nano.
Then restart Apache
sudo service apache2 restart
Change using command line
sed -i 's/memory_limit = .*/memory_limit = 64M/'/etc/php/7.0/apache2/php.ini
Set the memory value in WordPress
sudo nano wp-config.php
Add the following line:
define('WP_MEMORY_LIMIT', '256M');
define(‘WP_MEMORY_LIMIT’, ’64M’);
Extending WordPress memory limit in .htaccess
