When you enable the system and language debug in the Global Configuration of Joomla! 1.6 and refresh the front-end, you will find parsing errors in file en-GB.tpl:ja_t3_blank.ini in the debug position.
This is because spaces are entered in the keys what is incorrect in the Joomla! 1.6 language .ini files to be compliant with the ini standard specifications.
Yeah, and it would be highly appreciated if you used real Joomla! 1.6 language keys, like:
TPL_JAT3_YOU_ARE_HERE="You are here:"
TPL_JAT3_BACKTOTOP="Back to Top"
TPL_JAT3_TOP="Top"
etc. or something similar.
