Strange message after installing plugin
-
After installing the plugin EWWW Image Optimizer, I see this message:
EWWW Image Optimizer requires exec() or an API key. Your system administrator has disabled the exec() function, ask them to enable it.
However, below there is another message:
Plugin Status All ClearI want to run the Bulk Optimize but I am not sure if it will cause a disaster. May I safely run it?
Thanks
Miguel

exec() is plainly disabled, so the warning is correct, you need to see if you can get that enabled by your webhost, or use the API: https://ewww.io/plans/I’ll have to double-check why the status area gives an all clear on that though, as it should say “Needs Attention” or something to that effect.
First off I’m confirming that on a site I’m working on now, although exec() is disabled the status area gives ‘All Clear’.
Now, one question if I may. I see the issue with disabled php functions is much common in shared hostings. Couldn’t
ini_set()be used for the use of the certain plugin to avoid these problems?Most hosting providers won’t enable the exec() function.
Thanks for that confirmation, haven’t had a chance to dig into the “why” yet. At any rate, the disabled functions is a setting that cannot be overridden. Once it is set, that’s it.
And I wouldn’t say most, because the list of known working providers is much larger than the list of non-working providers. And, (roughly) 99% of all EWWW users are not using the API.
Regardless, the folks who have exec() disabled by their webhosts are exactly why I created the API. That way they can still use EWWW, and avoid any restrictions a webhost might have in place.
