Hi
Thanks for assisting
I am pretty sure I did both of those measures...
I tried 2 different ways:
1)
Change template name
Change templateDetails.xml so that all references to template (including language files) are changed accordingly from old name to new name
2)
Changed only template name
Kept templateDetails.xml 's language file reference unchanged, and made sure the language files were in my_template/language
Both ways had same effect
I know I must be doing something wrong...
It seems that some of the language overrides are found and some are not found.... (that started my confusion over which language files were for which part of site)
If you think it's me being a donut let me know, I don't want to waste anyones time if I'm doing something stupid....
if you think there is more going on than me just being a donut let me know
