Here's what you need to do...
In the Lite_Grey template, you will see a folder called languages.
Inside that folder you will see one called english.
Inside that, you will see one called lite_grey
You now need to send THAT folder (lite_grey) to your HUNGARIAN language folder.
So, on your SERVER, go via FTP to
includes/languages/hungarian
On your HOME computer, use the other FTP frame to go to:
Lite_Grey_Template/includes/languages/english
... then, ftp the lite_grey folder to your hungarian language folder.
You see... the template does not know that you are using Hungarian language pack. It provides for ENGLISH only, so you must send a COPY of what they provide for the English defines, for your Hungarian defines also.
When you have competed the procedure (above) your menu will be in English (whether you choose english or hungarian), but you will now be able to write in hungarian words into the right place.
