Hi Istvan,
I'm aware of Django translation framework, but BioStar structure is much more complex, as you have acknowledged (for example, the post types are hard to translate). But it seems it's not directly related to the issue I am having.
The story looks as follows: certain portions of python files are changed (no translations of hard parts yet, only settings.py, models.py, etc.). Everything works fine. However, after translation and replacing Markdown-flavoured editor with CKeditor, an attempt to vote gives me 403 (unable to submit vote), but I have no response on the Django side. Anyway, the issue has been submitted and diff file provided.
Thanks!
