Not fully working with database / importing old comments

Could not manage this plugin to make it working. Seems like it won’t touch database (it can only store one test comment that I made and literally nothing more, I could not even find any other data in MySQL database related to this plugin). Initially the comments were made on blogger, but I mapped urls to wordpress format.

1. All comments were migrated from blogger, urls were remapped to remove a blogger’s .html suffix
2. I am working on OVH hosting which is not that bad (not a free one at least)
3. the domain name did not change after migration
4. MySQL 5.5
