 * I have a problem with the site project which I was creating in Elementor. For
   the project needs I’ve created a subdomain with /test added to the address. When
   I finished basic project I wanted to replace the domain with the final address.
   After replacing the url some issue appeared and now I cannot do any update in
   current projects. When I click on “save changes” I receive information that there
   is serwer error (400 bad request). Even if I want to make new site project I 
   can only add few sections 3-4 and than again I am blocked with this message. 
   I was trying to copy elements from current projects and paste it to new, but 
   there is the same situation. I can copy and paste 3-4 sections and than again
   I am clocked. Do you have any idea what I can do instead of reinstalling wordpress
   and do everything once again? I had only few small changes to apply. Can enyone
   help?
