I have the latest version, just downloaded today. Mediafiles all got optimized without problem. Next step was Nextgen galleries. I get this screen: NextGEN Gallery Bulk Optimize
When I click start optimizing, the screen refreshes after few seconds and comes back the same.´
This tool can optimize large batches (or all) of images from your media library.We have 546 images to optimize.
This is my plugin status info:
If updated versions are available below, you may need to enable write permission on the wp-content/ewww folder to use the automatic installs.
*Updates are optional, but may contain increased optimization or security patches
