ChatGPT saying Unknown Error Occurred for File Uploads

Since OpenAI apparently has no interest in fixing this error (or “functionality”?), I have switched my coding tasks to Gemini. I suggest the same for others with this issue.

Getting this stupid error for every single file I upload.

I easily fixed it by changing browser

it is EMBARASSING that you guys are an AI company that can’t figure out a simple image upload. Just WOW!

Today 05-March-2026, I am facing this same error during uploading programming .php, .css, .ts files while I have cleared cache and cookies but the issue is not solved.
