Thank you for your response. I tried what you suggested, but it didn’t work.
I still can’t identify the problem with my blog. Recently, I discover that clearing the domain cookies solves the problem for a while. This is useful to keep developing my site, but it’s not a solution because at some point the page ends up crashing again.
I was wondering if this issue could be related with my hosting, but they don’t want to help me because they can’t see the problem. Besides, they say that everything is running ok.
Please, any other suggestion?
