Basic System Requirements

Lower limits may interfere with normal functioning of WordPress, theme and plugins…esp demo import

Item Recommended Value If low
memory_limit 256M or higher (e.g., 512M) – Incomplete Imports / Demo Import failure
– Failed Plugin/Theme Activation
– Allowed memory size exhausted error
– Internal Server Errors
– Plugins or themes may not function properly
– Site Crashes
WP_MEMORY_LIMIT 128M may work OR 256M

If you have multiple WordPress instances…try with lower first.
Or you can increase to 128M or 256M and once demo is imported can reduce it to 64M
If not facing any issue while editing with 64M…can keep the same.

 – Incomplete Imports / Demo Import failure
– Allowed memory size exhausted error
– Internal Server Errors
– Plugins or themes may not function properly
– Dashboard Issues
post_max_size 64M A higher value is needed for uploading larger files (e.g., images, product data) through WooCommerce or page builders. If it’s too low, large form submissions or media uploads may fail.
upload_max_filesize 64M You may want to allow higher upload sizes if you are uploading large images or files for your products or pages. Lower values may cause issues with uploading large product images, media files, or any content that needs to be uploaded via the WordPress admin.
max_execution_time 300 A higher value is recommended for large WooCommerce stores and page builders, which can take time to load or process complex content. If too low, it could interrupt things like product imports, backup processes, or large page builds.
