Hi Peter,
I believe what you're saying...I do think Corona and Brightbox use same framework and so WPML integration should be the same...
BUT IF IT'S TRUE...why only on Brightbox official theme page
http://themeforest.net/item/brightbox-business-portfolio-wordpress-theme/233917
there's WPML badge and you can read "Multilingual ready" ?!?
On Corona official theme page
http://themeforest.net/item/corona-business-portfolio-theme/533913
there's NOT any WPML reference...
Also on WPML compatibility themes page Corona is not mentioned (while Brightbox IS):
http://wpml.org/documentation/theme-compatibility/
So...could you kindly ask Kriesi which is the correct interpretation:
1) Brightbox is ACTUALLY WPML ready and does NOT need any changes (for portfolio too)
2) Both Brightbox and Corona CAN BE integrated with WPML but they BOTH need changes on theme core in order to do that (so WPML badge on Brightbox official page could be partially inopportune)
3) Both Brightbox and Corona are ALREADY and ACTUALLY WPML ready and do NOT need any changes (for portfolio too)
Thanks in advance for explanation!
Best regards
