Redirect loop problem- how can I stop it?

Hello I have a redirection loop problem with the page I am trying to make: http://www.trade-gate.net. Unfortuantely I don’t know much about coding. The problem started when I renamed some of the pages that are under my website. I renamed some pages several times I am afraid – not knowing that this might be a problem. Now I understand that all those records were kept somewhere in the memory of wordpress and authomatically wordpress keeps directing them to one another causing an infinite loop. I do not know how to stop it or erase the previous data on the page names.

I don’t know how I will solve this. I read several forum posts but I am not quite clear on any and if I touch the htaccess file-as it is recommended in several posts, I am afraid that everything will clash.Because each recommendation involves several different codes.

I think there should be a simple solution to this because it can be encountered so easily while renaming pages.

This is an example for several of my pages with redirection loop problem: http://www.trade-gate.net/eurostrong-televizyon-koltuklari/

Can you please advise a solution for me? What should I do?

I thank you in advance for your help.
