Selected files never show up in the browser window

Or is there more code I can edit to fix this on mobile?

I have a feeling that if I buy the theme and ask support, they're not going to help me with a plugin. 

What's up with the Kale theme on mobile that the desktop fix didn't work on mobile? 

Hi @tgw,

Is there a list of themes confirmed to work fully with WPforo? The themes you develop/test on?

wpForo developers have made the plugin maximumly compatible with other WordPress plugins and themes. There are a little number of plugins/themes that conflict with wpForo. All these topics can be found under the plug-in conflict tag.

This issue doesn't come form wpForo Advanced Attachments add-on, to make sure, just switch to some default theme and check again. The theme develops should know the best way to solve the issue. As you may see the code provided by our developers solve the issue partially.
