Hi,
thank you for let us know about this,
1) Please go to your team_tc.php file in Elements folder
(you can find it here \wp-content\themes\shard\elements)
and go to line 224 and 229 and replace ABdev-shard
with ABdev_shard
.
2) Go to your comments.php file (you can find it here \wp-content\themes\shard\partials)
at line 135, there you have ABdev_jomelle
. Replace that with ABdev_shard
.
In this file you have ABdev_jomelle
in more places so please replace all of them with ABdev_shard
. Thank you.
3) Read second solution because it is the same file :)
Cheers
