500 internal server error on all pages

Question

I have moved my site from this like to here. During the migration I changed the urls from all over the site so it could work properly in the new domain. Now I am getting 500 Internal Server Error message on all of the website's pages except the homepage. Please guide me how can I remove it?

Answer 1

I went to my website's permalink settings and choose a different permalink setting and hit save. The links started to work properly. Then I again went back and make permalinks the old custom posts way and it still is working properly.
