Are you looking to find out what is number of comments in each site in a WordPress network? This can be done with Beyond Multisite by previewing a comment deletion task with the Cleanup module.
We can see all comments or choose some criteria to filter the search. For example only older comments can be targeted or only pending or spam. Also some (selected by ID) or all sites can be affected.
Follow these steps:
- From the Network Admin Screen click on Dashboard -> Network Cleanup
- In the Delete Comments section choose the criteria in the form or leave it ti see all comments.
- Click Preview Comment Deletion
Now you see a list of site and the comment count in the For deletion column.
