Just taking a guess, but did you change your conf/_basic_config.php file to reflect the new path?

Yes, that is the first thing I did. By the way non of my blogs links work either. They give the same error.

Let's hope someone smarter comes along because - to the best of my knowledge - it shouldn't make URLs out of old settings for $baseurl. I mean it's not stored in the database. ... or is it? Can you take a peek at your evo_settings table and see if "blog192" is in there anywhere? It never used to be, but I still run 1.8.6 so I might be unaware of a new thing. Actually maybe some other tables would be good to search, but I don't know which ones. Isn't there a table called evo_blogurl?

Oh hey that could be it! A blog-specific setting that still knows about "blog192", which you wouldn't be able to change until you can get to your back office, which you can't do until you change it. It's worth looking at the tables I think.

Sorry EdB, I found the mistake and it was stupid. As you suggested it was in

conf/_basic_config.php

When I changed /blogs192/ I changed it to /blogs/ instead of /blog/

I forgot the "s".
