@rosbif, It's already there - see docs for where to uncomment the code. macavity found an issue with using it on v3 or later, but the patch is trivial.
change line from:
| Code:: |
ProNews::dyn_meta_tags($row['ctitle'],$row['title'],$ introtext); |
to:
| Code:: |
ProNews::dyn_meta_tags($row['ctitle'],$row['title'],decode_bb_all($ row ['intro'], 1, true)); |
as $introtext no longer exists.
