Found the answere. It was strange because when I turned off the plugin Polilang – the website started to work or course not in 2 languages. I found the answer in this article – http://www.wpbeginner.com/wp-tutorials/how-to-fix-error-too-many-redirects-issue-in-wordpress/ Sorry for bothering. Have a great day.
Nope – still having the problems. The English version of the website is working, the Polish doesn’t – Err redirect… 🙁 Actually so far no ideas. Help if possible.
I had the same problem
My wordpress adress and site adress where the same and I installed polylang, as it added the language “/en/” in all urls it also created a website example.com/en, which was basically a list of posts…
My fix was in Settings – General
Wordpress Address URL http://example.com/en
Site address URL http://example.com
Now your Home or Front page has a URL as the TITLE, I changed the SLUG with Quick Edit to “index” and that was it
Sry, in my polylang setting I have selected
The front page url contains the language code instead of the page name or page id
Example: http://example.com/en/ instead of http://example.com/en/index/
you can also try selecting and unselecting that option
