To start, I've gotten it working on other sites but not this one. What happens is, I click the "Minify My Site" button and it does its scan, but that's all it does. It never brings up the usual options of move this here or there. I have tried the following below.
1. Disable all but hummingbird, didn't work
2. Changed theme (its custom), didn't work
3. Uninstalled and re-installed the plugin in case files were missing, didn't work
4. Tried to "Reset Settings" button at the top of hummingbird, didn't work
It is a development environment so you will need the login info below to view the test site. Any help is welcome.
