I was using italian language.
I changed the name of a set of pages, using white spaces.
After that was impossible to access editing page of set pages (blank page) and to access the wizard.
So I changed the language (to english) and all was ok.
Now I'm waiting (from the company who manage my server) db login parameters to edit the name with white spaces and think all would be ok.

Is this only my configuration issue or is it a bug?

Thanks.

 

The problem was due to the presence of hyphen in the names of a page of page set.
Well, this page comes with original files from swsoft.
As I said in an another post, it seems that there's a missing addslashes or something similar.
