Any PNG gives an error, and I’ve tried loads

This only gives an error when uploading via the post / page / media editor
When uploading via listings on my site (listing site) it seems to be fine.

My developers have advised it’s your plugin that causes the error.

Running it on multisite if that helps.

It’s quite urgent I get this fixed.
Thanks

PNG optimization is much slower than JPG optimization, so it’s probably just timing out. Especially if you’re uploading any largish PNGs, this can be problematic.
You can start by setting optipng and pngout back to the defaults (level 2). If that doesn’t fix it, then turn off pngout. If that still causes problems, set optipng to level 1. If you’re still having problems, then your images are crazy huge, and probably ought to be JPGs instead.
