    Greetings. We have several dozen installations of your plugin running on our servers and ever since upgrading to version 1.7.1 they all get the message: “Safe Mode is turned on for PHP. This plugin cannot operate in Safe Mode.” Safe mode is disabled in php.ini for every wordpress installation we have.
    Here are typical relevant info from a phpinfo():
    PHP Version 5.3.26

    While safe mode is available to turn on (‘–enable-safe-mode’) it is off in the php.ini (safe_mode = Off) and this is verified by phpinfo().

    We would of course like to get your popular plugin working on our servers.

    Added note: One of our developers suggests that you might be checking ini_get(‘safe_mode’ agaist only the boolean and not also “Off” and the somewhat unlikely, but still possible “off”. Our servers need safe_mode = Off not safe_mode = 0 .

    Could this be the issue?

    That is a good possibility, I’ll check into it before I release 1.7.5

    Thanks! Here is a link to some discussion of this issue: that might be helpful. ??

    I think I’ve got it fixed in dev, releasing a bit later after I do some testing. I don’t have any machines with php 5.3 anymore, so I had to fire up a new vm real quick on my host.

    Ok, definitely fixed now, releasing shortly.

    Thanks! Five Stars to you, and EWWW Image Optimizer!
    Your Plugin saves our clients a great deal and makes their sites load even faster.

    Note: Most of our servers are on more recent PHP versions. Though, some of our customers aren’t ready to switch yet and are still on EOL/Depreciated versions of PHP. In a few months, they will all be on versions that don’t even have the possibility of Safe Mode (not that is being used now). But we really appreciate your excellent service and responsiveness none the less.

    BTW, I should clarify that we made an error in our original post. After checking our client upgrade notes we know the issue began after the upgrade to WordPress 3.7.1 from version 3.7. Prior to installing your next version. Something likely changed in WordPress that caused the issue to surface. The plugin is certainly well crafted, and of course is well maintained.
