Select the bot application > Make suare the Bot Token and Client Application ID Match. Maybe even try generating a new token?
Hey man. In my 2nd post I said I already tried remaking the bot. Deepbot has a Bot Token and Client Application ID stored correctly, but Connect is greyed out and cannot be clicked. The first time you load up Deepbot, if you try to click Connect, despite the button not being clickable (doesn't even turn blue on mouse over), the Master Settings page jumps up halfway up the page and you have to scroll down to the Discord section again. From then on, you still can't click it, it doesn't do anything. Join Server works, it opens a web browser and asks me to confirm I want to give the bot rights in my Discord server, as well as selecting my Discord server in the dropdown.
I appreciate you trying to help but if you're the only person I'm going to get to talk to about this, I need you to move past simple setup stuff, as my problem seems to be deeper than that. The Bot Token it has stored doesn't match the one on the website where the bot is made (what you linked), and if I try to change the Bot Token in Deepbot, and click Save, when I go back into Master Settings, it will be the old one again. It's also got a channel in Monitor Channels and Broadcast Channels that I deleted in Discord, so it isn't updating in any way.
