Issue with OAuth Registration: 500 Internal Server Error

richjr93

I am encountering an issue when trying to register using OAuth on my Flarum forum. After clicking "Sign Up," I receive a 500 Internal Server Error.

Here's what I see in console:
Application.tsx:522
POST https://discuss.example.com/register 500 (Internal Server Error)

*This happens in the actual server. It works fine in local environment. What did I miss?

I am using the fof/oauth extension(https://flarum.org/extension/fof/oauth) for OAuth functionality.
The issue occurs with all OAuth providers I have configured.
I am using Flarum 1.8.10

I hope someone would help me.

Thank you!

Update: OAuth Failing Due to allow_url_fopen Restriction

I ran into an issue where OAuth login was failing because my hosting provider does not allow allow_url_fopen to be enabled. This caused the avatar upload from a URL to fail in Flarum’s core file, specifically:

📂 vendor/flarum/core/src/User/Command/RegisterUserHandler.php

The issue occurs in the uploadAvatarFromUrl function, which uses Intervention\Image\ImageManager->make($url). This method relies on file_get_contents() internally, which my hosting provider restricts.

Solution That Worked:

To fix this, I modified the core file and replaced file_get_contents() with cURL inside the uploadAvatarFromUrl function. This allowed OAuth avatars to be fetched successfully without relying on allow_url_fopen.

Need Help with a Better Approach

Since modifying core files is not recommended, I’d like to apply this fix within an extension instead (e.g., in fof/oauth). The issue is clear, I just need to find a way to override the method without altering the core.

If anyone would help me properly override uploadAvatarFromUrl within the extension, I’d really appreciate your guidance. Thanks! 😊
