[SOLVED] ReferenceError: Class is not defined (frontend submit form)

hi there,

[my problem]
i get a "ReferenceError: Class is not defined" when i visit my frontend submit-page.
the error comes from
/components/com_flexicontent/assets/js/itemscreen.js ~ line 1
and
/components/com_flexicontent/assets/js/validate.js ~ line 35

Any hint on what exactly i need to turn on / allow / load is greatly appreciated.
thanks, kath

hello => to help you flexicontent version + joomla version
thanks

oops, sorry:
Joomla! 3.4.2
FC 3.0.0 BETA7g
thanks

Hello

click CTRL-F5 or similar to make sure you have latest JS
make sure that jQuery is loaded once (the Joomla way)

hi G,

>> click CTRL-F5 or similar to make sure you have latest JS
done, with same result.

>> make sure that jQuery is loaded once (the Joomla way).
done, with same result. In more detail:

- The error happens only on my frontend-submit-page.
- The error happens there even if i unpublish all of my custom fields.

my setup:
Joomla 3.4.3
FLEXIcontent 3.0.0 BETA7g
Question for a quickfix:
If I knew from where the "Class"-class definition is supposed to come, i could -for now- provide it manually. So: Is that a FC-file or a Joomla-file?

thanks a lot!
kath

question => the error is only on front end ?
can you try to change template for protostar to test ?
