Comment (by Pixeldrummer):

 Will check with our server people re: upload_max_filesize and
 post_max_size, as far as I know they are set to 32 MB and are occasionally
 increased to 64 MB, I'll confirm.

 Am not running multi-site and have tested with themes other than X and the
 problem did not appear, only on the 3 sites I updated with X. These are
 live sites, some large, cannot test with any twenty *. The file size
 problem only appeared after updating to '''WP 4.5.1'''. I'll post back
 with the filesize settings.

 > I've assumed this was a PHP configuration problem as the error message
 and the limit match exactly the (old) default in PHP. Could you check what
 are the values of `upload_max_filesize` and `post_max_size` to rule them
 out.  Also, could you experiment with several different themes (including
 the default Twenty *) to confirm if this is caused only by that theme or
 is more common.

 resizing uploaded images, but then PHP will run out of memory and the
 error message will be different.
