Im not sure whats going on. This plugin worked great before. Now it's complaining about file permissions I have tried everything up to and including 777. Ive removed the -linux, and then finally just copied the old OptiPNG version 0.7.4 and old LCDF Gifsicle 1.68 into a new ewww folder.
everything reads ok
jpegtran: OK version: Independent JPEG Group's JPEGTRAN, version 9 13-Jan-2013
optipng: OK version: OptiPNG version 0.7.4
gifsicle: OK version: LCDF Gifsicle 1.68
Graphics libraries (only used for conversion, not optimization): GD: OK Imagemagick 'convert': MISSING
safe mode: Off exec(): OK shell_exec(): OK
Only need one of these: finfo: OK getimagesize(): OK mime_content_type(): OK
except...the red content warning box will not go away.
EWWW Image Optimizer couldn't install optipng and gifsicle in /var/www/example.com/htdocs/wp-content/ewww/. Please adjust permissions or create the folder. If you have installed the tools elsewhere on your system, check the option to 'Use system paths'.
it seems something is wrong. what i have no idea. This is the third attempt to update this plugin resulting in failure. Seems everythin is working I just cannot figure out why it is complaing about the ewww folder permissions.
great plugin up till now....
