D4rk56 Your problem is as it's showing my friend. "flarum-ext-oauth-discord v1.0.1beta6 requires flarum/core v0.1.0-beta.6" but you are now using beta 7. You can go at that in three ways:
- Update the discord extension seeing as there were changes committed by @luceos which changes the requirement to be v0.1.0-beta.6 up from v0.1.0-beta.6 (Which basically means that if it doesn't equal beta 6 or below, the requirements are not met).
- Manually update that extensions composer.json to require v0.1.0-beta.6 or simply go with option 1.
- Remove the extension.
I'd go with option 1 personally but keep your Discord API credentials ready in case of any potential bugs (not all extensions have been tested for beta 7 that I know of).
