I've tried several times to enter our Google Analytics tracking ID but it doesn't seem to save properly even though it says save. After save then ID field is empty again. Also when checking real time stats in Google there is no traffic or activity.

Please assist. (See screenshot it keeps removing the ID)

If plugin does not work, submit bug to osclass team to provide fix/update.

Thanks @frosticek. I removed the plugin completely and reinstalled it - seems to have worked.
