News Tutorial

Hello,
I'm new to CI4, and I'm trying to work through the tutorials. I got as far as the form for posting data, where, upon submitting new data, I get:

I really don't know what I've done wrong. I would really appreciate some help. Also, if I've missed anything, please let me know. Thanks in advance.

The error message comes from Apache.
Your Apache configuration is not correct.
Check the Apache configuration.

Perfect! Thanks! It had to do with how I had configured the baseURL, and I didn't notice.
