 * Hi,
 * I have purchaseda cloud key but am getting the following error – EWWW Image Optimizer
   requires exec(). Your system administrator has disabled this function.
 * I didnt think exec() was needed when using cloud. The plugin has been working
   fine for 12 months and nothing has changed at my end that I’m aware of.

 * If you change either JPG or PNG to regular “lossless” then it is not using the
   API, bump it up a level and the message should go away.
