Its your theme issue.
Follow this: https://anspress.io/questions/question/bug-following-does-not-work/ Update you pot file using ap.po
Its because you have not updated plugin as per general procedure, instead you you just replaced the file. For fixing this just deactivate and re-activate AnsPress and our activation hook will trigger and add required tables (which got added in 2.4).
You can override AnsPress theme from a child theme and parent theme. By default AnsPress looks inside child theme for override and then parent theme. This is useful when you are using child theme.
You can have both installed at the same time, and each will do its own thing. The shame is that Postmatic Social Commenting has no plans to do site signup, and Social Login Plugin won’t authenticate comments. They are two separate environments and each sees the world very differently. How do I know? I asked them both the same question.
Are you using AskBug? if so, update is available for download.
