WordPress site redirecting to developers URL

This is very vague and little information. There could be tons of reason for this. Try some of the following and see if it fixes your problem.

  1. Permalink Refresh: Goto Settings > Permalink and hit “Save Changes”
  2. Check WP and site address: In Settings > General check if the WP address and site address are reflecting the URL you want.

Hereafter, please try to phrase and explain your question properly including the site URL and the steps that you already performed.
