Hello! I am posting a question about a problem on my blog http://periferiesurbanes.org
When I click on "older posts" at the bottom of the first page, I am redirected to http://periferiesurbanes.org%2f%3flang%3den&paged=2/
which gaves me "problem loading page"
This represents a problem for me because it makes almost completely unaccessible some posts, for example those who have no categories... and difficult to access many others.
Can you help me to fix it?
