jpavlicek on "[Plugin: EWWW Image Optimizer] Freezing/not optimizing images in 2.9.3"

Hey,

perhaps I've found what causes the problems. I changed the following in background.php on lines 232 and 236 …
from $file_path = ABSPATH . $_POST['ewwwio_path'];
to $file_path = $_POST['ewwwio_path'];

That solved my problems. The plugin tried to concenate two absolute paths and therefore couldn't find the file.
