Increasing memory limit in WordPress

Sunshine does have a few functions that can require higher memory limits than are the default – especially when it comes to uploading high resolution images or when downloading large zip files of digital negatives. One thing to try is increasing the available memory your server/WordPress/Sunshine has access to so the process can properly run.

There are two places where the maximum allowed memory is set: At the server level and in WordPress.

If you go to Sunshine > Server Info you can see there are two lines for “PHP Memory Limit” and “WordPress Memory Limit”. We want those to be as high as possible.

Step 1

First step is to change the memory limit in WordPress as this is required no matter what.

Edit your wp-config.php file and add the following:

define('WP_MEMORY_LIMIT', '256M');

We want this as high as possible that your server will allow. So look at your “PHP Memory Limit” (as described above) and match that number.

Step 2

Next step is to ask your web host to increase your available PHP memory to the max they allow.
