please help me guys.

What script are you using?

I have the exact same problem, when I tried to add Google maps to my wordpress website. Can’t acces any page, having the feeling I made a big mistake. Any way to solve this? Thanks in advance.

UPDATE: SOLVED automatically. Maybe it wasn’t because of my google maps script, but after 5min I was able to get in again. Probably coincidental, and me being too impatient.
