First, I would like to say that I love the plugin. I find it so much easier to use than other plugins of similar nature. Thank you for all your hard work!
I would simply like to report a conflict with the following setup:
WordPress 3.7.1 - 3.8
NextGEN Gallery Optimizer Version 1.1.2
NextGEN Gallery by Photocrati Version 2.0.40
Issue noticed with the bulk media smush.it feature.
When you run the feature, it produces a bunch of crazy symbols where it would normally go through your media files and optimize your images.
The simple resolution was to disable the conflicting plugins, proceed with the bulk media smush.it and then reactive the conflicting plugins and deactivate WP Shush.it.
Thank you again for such a great tool. I hope you find this information helpful with your future developments.
