Sorry for my english.
before update to wppa+ 5.3.2 all images was stored in /blogs.dir/…/ (WordPress 3.9 and Multisite).
After update to wppa+ 5.3.2 the images path was changed to wp-content/uploads/admin/wppa/.
I found this in wppa.php
To run WPPA+ in a multisite old style mode, add to wp-config.php:
define ('WPPA_MULTISITE_BLOGSDIR', true);
