Hi Cindy!! As the CommentStreams extension page states, latest version of the extension is supported by;
| MediaWiki | 1.25+ |
| PHP | 5.5+ |
Whereas, I have Mediawiki of 1.25.2 and PHP version of 5.5.9-1. Shouldn't it work normally? But I get error of;
MediaWiki Extension:CommentStreams, undefined constant DB_REPLICA error. And when I try to save comment it gives <unknownerror> on pop up window. After a long research I found out that my Mediawiki might not be compatible to the latest version of the extension. So I downloaded the CommentStreams version 4.0. Now the DB_REPLICA error is gone but still giving me the error of <unknownerror> while I want to add comment. Could you please help me with this? Thanks in advance.
