Automatic post to Facebook and Instagram

[kmk]

How can I configure my IPS, that let my members manage blog, when they post an entry, it posted automatically in their FB and IG accounts?

There is no built in way to do this, and frankly Facebook, et al don't want you to either. You can link your Facebook and Twitter accounts to use the "Promote" tool within the software, which is a moderator/admin-level feature.
