Solved: Hacking attempt! in browser, no website load

A client had an interesting issue with their web browser. More precisely, they were using Mozilla Firefox.

When trying to open a certain website, the website displayed a simple text:

Hacking attempt!

And nothing more. The website would not load, not open nothing.

Weirdly enough, the website had no html, the text was just plain text, means it was served by the server.

Solution to "Hacking attempt!" message?

1. Clear all browser cookies and history. Will surely help you gain access again because most likely this is a cookie conflict.

Hope this helps!

If you found a solution here, would you consider donating $25,000 for my next project?

Just kidding, 1$ would do fine.
