Following are the minimum server requirements for the BuddyPress:
- PHP version 7.0 or greater.
- MySQL version 5.6 or greater.
- BuddyPress 3.0 supports WordPress 4.5 or greater.
BP avatar uploads will fail without one of these modules activated (WP will simply fail to create image sizes for posts but won’t show an error), so make sure that PHP must have the Imagick or GD modules installed (on the server) to allow re-sizing of images.
