Reduce file sizes for images within WordPress including NextGEN, GRAND FlAGallery and more. Uses jpegtran, optipng, pngout, pngquant, gifsicle, cwebp,
Though the problem mentioned by all other below here is true i.e. exec() is ever required which never gets up and running! I came across another issue. When I tried deleting this plugin, it left some residues in my /wp-content/ewwww folder like: pngquant, optipng, jpegtran-custom, jpegtran, gifsicle. I don't know what extensions are for those files!! Even FileZilla couldn't determine its Filetype.
Furthermore, it automatically changed Owner/Group to somebody else and setting File Permissions to 755!! I've contacted my host provider to delete it for me!! Waiting for their reply..
This plugin didn't work for me and was frustrating to delete this residues it left after uninstall!! Very buggy!! :((
You'll probably get this error message:
EWWW Image Optimizer requires exec(). Your system administrator has disabled this function
Unless you want to waste time searching for solutions and getting your server to turn on exec() whatever it is (and is it even safe to do so??) just don't bother with this plugin.
Tried everything in installation instructions over and over, just does not work. Can be my host blocks this, but for me this plugin is pretty useless
Must be another plugin installed.
this is not usable...
And i'am using shared hosting...
i can not install additional plugins...
