Error in Step 2 of the 'New Feed Wizard'

Describe the bug
I can't add a new feed with 'New Feed Wizard'. I encountered a Fatal error in 'Step 2 - Select Article Text' after selecting text, clicking on 'Get' and then clicking on 'Next'.

Error message

Warning: Undefined array key "host" in C:\xampp\htdocs\lwt\feed_wizard.php on line 439

To Reproduce
Steps to reproduce the behavior:

1. Go to 'Newsfeeds '

Hi! Thank you for your detailed system report! I have tried applying the same procedure and ran into the same issue. I think the kind of feeds you want to use are to complex to work with LWT. I have tried some advanced feed import settings without more success than you.

The feed wizard feature was not developed by me, does not work so well and it is too complex to maintain. It's better to avoid using it for now.

Hi, thank you for your quick response. I thought maybe I was doing something wrong. I will try it with simpler feeds or copy and paste the articles manually. By the way, great job with this fork :)

I improved the situation a bit I think in 06ae857 as the errors appears in step 3, but is still the same.

I also improved code readability, and fixed some JS issues on the feed wizard 0a36899, but I could not debug the code, as it is too complex to read. I hope it won't be too inconvenient for you...

Thank you for your support, I'm setting this issue as help wanted as I couldn't find a solution. However, I think only a total rewrite of the feature could work here.

Have a great day!

I appreciate your efforts to refactor and improve the whole repo and fix this bug. Unfortunately right now I don't have enough knowledge in these programming languages to help you. I hope you get help soon.

Have a nice day!
