Hello, 

I am doing my first worksheet ever and I have problems with uploading my PDF worksheet.

It says that I have problems with my Browser's developer console.

Can you help me, please?

Hello!
We are here to help you get past this initial hurdle.

The "Browser's developer console" error usually happens when a strict browser extension, a built-in ad-blocker, or accumulated cache blocks our upload scripts from processing your PDF file.

To resolve this quickly, please try these simple troubleshooting steps:

- Clear your browser's history and cookies, then restart the browser. We highly recommend using an updated version of Google Chrome.

- Temporarily turn off any ad-blockers, antivirus extensions, or privacy shields (like Brave's shields) for our website.

- Open a private/incognito window, log into your account, and try uploading the PDF there. If it works, a browser extension is the culprit.

I hope this helps. Let us know if the issue persists.
