I have copied the default Beez3 template to another name in order to customize the design and layout without disturbing the original template. Most modifications are taking place in the copy's personal.css file.
I have also changed the constant names in the file /templates/mytemplatename/language/en-GB/en-GB-tpl_tps.ini from TPL_BEEZ3_* to TPL_TPS_* to remove references to the Beez3 template.
Since changing those constant names, the site now displays those constant names instead of the values defined in the .ini file. The text links for changing the font size also displays 'undefined'.
Exactly how do I fix this ?? Any tips greatly appreciated !
