I hope it is not for the 113th time someone asking this - I am experiencing some problems after applying translatable - sure I have ignored this - yes I am stupid
Important: If the "default language" of your site is not english (en_US), please ensure to set the appropriate default language for your content before building the database with Translatable enabled.
The existing content was en_US, I have added other 2 (cs_CZ, and en_GB) which are the ones I want on the site. I have changed the _config.php and rebuild. :)
EDIT: Is there a way to revert to the original status quo - to rebuild the database with the correct default locale (cs_CZ instead of en_US)?
Thank you very much
