Hello, I can't update my style on XenForo

Hello, I can't update my style on XenForo

When I try to update my theme by following your upgrade tutorial, I get an error message...

Here is the message:
Oops! We ran into some problems. Please try again later. More error details may be in the browser console.

Small precision, when I upload a style it works, but when I want to overwrite the existing style it gives me an error message...

I don't understand everything, please help me
Best regards
