Can't access backoffice after URL Change in SEO tab

[NPE]

I was making my way around the back office just recently got prestashop; anyways when i was looking in the SEO tab i changed the url my previous url was yourdomain/store/ and i changed it to /shop/. I changed only the 3rd input that had just the domain (i.e. /store/ to /shop/) all of a sudden my back office is inaccessible. The yourdomain/store/ url just redirects me to my main www.yourdomain.com.

 

What can i do to fix this? Please dont tell me i have to start all over lol. When i try to go to my admin log in page it gives me this screen then it just loops forever when i put in the right credentials and press log in, it just seems to be local host cause the page is not actually sending the input into those fields anywhere i think

Found out how to fix the problem by going into the phpMyAdmin in the pr_shop_url and changing it back to /store/. But now for some reason all my product images no longer show anything. and when i try to click on them they take me to a 404 error on my main domain.

 

What is wrong here? has anyone experienced this? i am assuming that there is a problem connecting to internet? cause at the bottom it doesnt even show the little facebook snippet. any help greatly appreciated
