Hello Team,

Since i upgrade my free version to the pro one, i can not use anymore the plugin.
Whenever i try to upload a picture i am getting an HTTP Error, the Send to Smush to just keep looping.

I did try to uninstall reinstall the plug in --> still facing the same issue
I did try to disable plugin and keep only Smush Pro --> still the same issue
i did test with a smaller picture 5 Mb size 2048x1365 --> still the same issue

When disable Smush pro i can upload picture without any error using library upload.

when enable it back getting an HTTP error.

Memory is set to 128 MB in WP-config.
i am running wordpress 4.2.2 with the Them Moto Blog.

PS: Was working fine with the free version :slight_smile:.

Your urgent help will be appreciate as i setting up a new site.
