I already tried 40+ prompt and different ways to fix this issue but its just not working. It looks like a style corruption but i just cant figure it out and v0 also cant, Max had a quick look aswell and said it was maybe the database connection, but i also tried it without the database stuff and it still happens and the errors after 2min of waiting also shows some kind of styling issues.

But still same problem. MarnixB (@marnix-3108) · 2025-10-10 Okay so update, in chat; https://v0.app/chat/duplicate-of-emwheels-order-platform-CkN9iznwVaa#F0sqZ1Pjeal7zpD6TPYGDYnkt2jErsIU i have deleted the global.css and layout.tsx, and refreshed the preview, and now everything is working… what is going on Xd. please check it out.. MarnixB (@marnix-3108) · 2025-10-10 The problem was that V0 kept generating a global.css in the file preview, but the app likely uses a layout / global.css file that already exists elsewhere in the codebase (possibly in a parent directory or a default Next.js layout) without the conflicting styling imports. Still seems like a bug to me since v0 couldnt fix my issue by itself… Pauline P. Narvas (@pawlean) · 2025-10-13 · ♥ 1 Hey, @marnix-3108! This is super helpful. Thank you! :smiley: We'll make sure that we get this feedback shared with the v0 team.
