I just installed and tried in the Media Library to Optimize my first image. But I got a page with this error.
Fatal error: Call to undefined function posix_getpwuid() in /home/content/83/10131583/html/wp-content/plugins/ewww-image-optimizer/ewww-image-optimizer.php on line 1104
Here is my plugin status page:
If updated versions are available below, you may need to enable write permission on the wp-content/ewww folder to use the automatic installs.
*Updates are optional, but may contain increased optimization or security patches
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 1.70
Graphics libraries - only need one, used for conversion, not optimization: GD: OK Imagemagick 'convert': OK
safe mode: Off exec(): OK file command not found on your systemnice command not found on your system (not required)
Only need one of these: finfo: OK getimagesize(): OK mime_content_type(): OK
It must be me - have I not set up something correctly? Can anyone help please?
