It happened twice (in local and in server). Both: Tiki
* Log in as admin.
* Go to "Admin>DSN"
* Enter a record: for instance,
(in my case, "user" and "ddbb" had the same word)
After clicking on save, the field "dsn" from the bottom
list of registered dsn's shows "0", instead of
After editing this record (cliking on the edit icon on
the right of the table raw), and setting "dsn" as
"mysql://user:password@localhost/ddbb" again, then the
record is registered succesfully this second time.
By the way, great feature this one of SQL Plugin (and
great documentation on tw.o about it! :-)
