Optipng is not working

Make sure you copied the binary, and didn’t move it completely out of the plugin folder. It is doing a size comparison, and if there is nothing to compare in the plugin folder, naturally it will keep complaining about it.

I downloaded both optipng and optipng-mac to my PC and uploaded them to the new folder. I didn’t move or deleted them in the plugin folder.

can you check the exact filesize of optipng in both folders (the plugins folder, and the ewww folder)?

The size of optipng is 990.020 Bytes, in both folders.

And can you also copy the plugin status section above the debug info?

Ah, so you don’t see a bright red box at the top of every page, just the one in the plugin status, correct? If so, try the latest dev version, or wait until 1.3.7 comes out. If you don’t care about optipng, you can also just ignore that message.

I don’t see a red box, but a yellow one ?? It says:

EWWW Image Optimizer requires jpegtran, optipng or pngout, and gifsicle. You are missing: optipng. Please install via the Settings Page. If the one-click install links don’t work for you, try the Installation Instructions.

Ah, I’ve just tried the latest dev version and it works ??

Am I going to receive the next updates even though I installed the dev version?

You shouldn’t get a notice for 1.3.7, but whenever there is a newer version than that (like 1.3.8) you should get an update notice.

Okay, thanks! ??
