The system does not record in the database

[Luis Maina]

sorry for my bad English.
these days I am installing the real estate version of Flynax and almost everything works perfect except that the system does not record information of new users, etc.
"Refresh" does not refresh the page. It stays as "loading" for ever. or if I want to add a new search engine, etc. it happens the same. some other things are ok. Can anybody help me?
