I've detected that the BeGreen theme is having a conflict with the Ultimate Member plugin.
I switched the theme to twentysixteen with all plugins activated that came with the latest BeGreen 1.0.3.1. and the Ultimate Member plugin works fine, however, when I switch it back to BeGreen, the plugin doesn't work as it should-can't save settings in plugin most importantly. The Ultimate Member plugin is something that's needed for our site. I've tried on several browsers and have the same issue. Could you please advise me on what can be done to resolve this? Try it on your side to see what I'm talking about - install it and go to the settings in the plugin and try to save after making a change.
It's definitely a conflict with the BeGreen theme. I'm assuming something to do with css built into theme, but I haven't added any custom css. Then again, that's just a guess.
