PolarCloud Plugin won't install

Plugins

Trying to install PolarCloud and it keeps throwing an error.

I actually had it installed before and it was working but something happened during an update and it no longer was in the list of installed Plugins.

Raspberry Pi 3 Model B Plus Rev 1.3
octopi_version: 0.15.1
pip: 9.0.3
python: 2.7.13
OctoPrint 1.4.2

The octoprint.log gives some interesting output.

Any ideas?octoprint.log (14.3 KB) plugin_pluginmanager_console.log (123.6 KB)

Seems plugin is using a long deprecated method of importing Babel - in OctoPrint 1.4.1 the dependency was updated and this was removed. All that needs to happen is the author to change flask.ext.babel to flask-babel I believe. I would open an issue on the plugins repo, to get it fixed.

Thanks! I'll go do that. In the meantime I'll try downgrading to the previous OctoPrint rev and see if that can help.

Seems it has been reported multiple times in that plugin, all to pretty much no response.
