Since you have anonymized your domain here and every entry you make looks identical, it is difficult to follow you. If you don’t want to show your website, can you please describe the problem with example domains? So example.com and example.info or similar.
So the domain is more or less doubled. Where exactly does this happen? When the page is simply called up or only at individual points?
Have a look under Tools > Site Health to see if you see any anomalies there.
Deactivate all plugins as a test and see if it disappears. Please note that you may have to clear your browser cache so that it does not execute the redirect again by itself.
there is nothing anomalies on site health. I did deactivated the plugins and the error still generated.
For me, the question of where exactly this happens is still open? When calling up the start page or when calling up every page on the web?
@threadi thank you for the question.
I am using redirection plugin, and I check the 404 error log and I see it there. I do not know what causing or where it is coming from.
The URLs in this list from this plugin are created by calls in the frontend. These can also be bot calls that call up completely cryptic URLs.
In this case, however, I don’t suspect a problem with the setting in your WordPress, but rather a spelling mistake. This is either contained in your website or somewhere external. The wrong spelling would be in HTML, for example:
<a href="https://example.com/http://example.com">Or also:
<a href="http://projectdmc.org/http://example.com">Correct would be:
<a href="http://example.com">You should find this place. I don’t know if the plugin also displays a referrer for the call there. If so, follow it and take a close look at the HTML code of the page. If it is your own website as the cause, you can adjust this at this point. If it is an external website, then contact the person who maintains it.
Thank you @threadi for the detailed reply. I have check everything on the website and everything seems to be correct. I noticed this issue when migrated the website to another web hosting.
The plugin does not tell me the referrer, but I see these and many more:

and the list goes on like this
The duplicate url issue seems to be solved, I did many troubleshooting steps and it was still there. I cleared the cache from the website and from cloudflare and now it is gone.
One thing to mention is that we use W3 Total Cache and in the browser settings we marked “Do not process 404 errors for static objects with WordPress” and so many 404 errors we have beeing have has gone. More about this can be found here https://projectdmc.org/support/topic/404-errors-causing-website-crash/
We still have one more issue that has been there for very long time.
We used to have a forum and a store, and deleted them at least 2 years ago.
The store is: http://www.example.com/store
The forum is: http://www.example.com/store
We still have 404 errors coming to the forum and the store, and the plugin is is not telling us where the trafic is coming from. I will just disregard them for now, if you have a seloution for it I would really appreciate it, otherwise I think it should be fine.
I really appreciate your effeort @threadi on helping on this matter. Thank you so much for your time.
I’m glad you were able to solve it.
With URLs from previously existing pages, you have to decide how you want to deal with them. The main criterion here should be SEO aspects, i.e. the findability of your site in search engines. If the URLs from previous pages are still linked elsewhere, you could redirect the calls if necessary (e.g. using a redirection plugin) to keep the users who call them up on your site. Nothing is more annoying for someone who calls up a link and sees a 404 page. Search engine bots would also follow suit. Or you can leave everything as it is.
If the topic is done for you, you are welcome to set it to solved.
perfect @threadi tank you so much.
