How do you increase the default wordpress file size limit? There are several different things to do:
- Increase the file size in Settings> Media or Network> Settings for multisite
- Increase the file size in php.ini (/etc/php-version-and-type-/php.ini)
Find these settings and change them to your desired file size:
Note that memory_limit must be larger than post_max_size must be larger than upload_max_filesize.
