im confused...i chose to be a patron to your business...and you are black-balling me b/c im asking questions about your product...i spent almost 200 dollars and as a courtesy you cant answer questions...are you serious?
Let me try and explain.
You purchased the CBSubs GPL membership and you are able to download and use the CBSubs GPL product (and documentation) as indicated in the CBSubs page here:
www.joomlapolis.com/cb-solutions/cbsubs
This also entitles you to any maintenance releases for the CBSubs GPL product for 1 year and you can also get timely support (same of next business day responses) on the CBSubs GPL support forums (this forum you posted to).
Any questions about other products (Community Builder, etc) should be posted on other forums (Professional or Advanced forums for Professional or Advanced members - or free forums for community driven support where users help each other).
Regarding your specific language string question is appears to be directly related to the CB Gallery add-on which is part of the Advanced or Professional membership which you do not appear to have (and looks like you never had this membership at least not with your username).
Where did you get the CB Gallery add-on?
Are you sure you downloaded it from here?
