since the last Seblod upgrade forms won't get submitted. The URL show http://www.mydomain.com/component/cck/ I do see parts of the template - without everything concerning Seblod itself. No error message at all.
found the error myself: For some reason all JavaScript got corrupted by the minifier and gzip. Disabling JavaScript minifying and compression brought back all JavaScript and form validation, as well as form forwarding.
