Sometimes, usually after server change or introduction of the cache plugins, the reactions from posts might “disappear” and you won’t be able to see them.

If you can’t see reactionas as shown in the image above, try the following:

• Go to WP Admin -> PeepSo -> Manage -> Reactions
• Individually disable and then immediately enable each reaction that you are using.

This is usually enough to have reactions showing up again.

You may (or may not) be required to to repeat this process if you change domain, or restore your site from the backup.
