According to my host exec() is enabled. I was instructed to copy a php.ini file to a folder where I want this functionality so I copied the file to ewww-image-optimizer folder in plugins and ewww in wp-content. When I run <? phpinfo(); ?> there is nothing about exec() being disabled so in theory the ewww plugin should work, however, I still get the "EWWW Image Optimizer requires exec()." message. What can I do to fix it or ask the hosting to fix? What could be causing this if exec() appears to be working?
