installation problem

Hi, I can’t install the plugin. I’m getting the following error, which I’ve attached as a link. I’m using this plugin on two WordPress installations on the same server and domain. The one in the subfolder works perfectly, but the one on the main site gives me an error. Both installations have the same plugins and use the Wordfence plugin. I’ve set it to Learning Mode. What’s wrong?
