Westminster Confession of Faith
Chapter I
Of Holy Scripture
....
VI. The whole counsel of God concerning all things necessary for His own glory, man's salvation, faith and life, is either expressly set down in Scripture, or by good and necessary consequence may be deduced from Scripture: unto which nothing at any time is to be added, whether by new revelations of the Spirit, or traditions of men.[12] Nevertheless, we acknowledge the inward illumination of the Spirit of God to be necessary for the saving understanding of such things as are revealed in the Word:[13] and that there are some circumstances concerning the worship of God, and government of the Church, common to human actions and societies, which are to be ordered by the light of nature, and Christian prudence, according to the general rules of the Word, which are always to be observed[14]

Generally, the issue is new revelation.
Revelation, especially what is called "special revelation" (as opposed to general revelation by nature) comes through the prophets and apostles
Ephesians 2:20 20And are built upon the foundation of the apostles and prophets, Jesus Christ himself being the chief corner stone;
who delivered the completed faith through Scripture
Jude 1:3
Beloved, when I gave all diligence to write unto you of the common salvation, it was needful for me to write unto you, and exhort you that ye should earnestly contend for the faith which was once delivered unto the saints.
The I Cor 12 spiritual gifts do not provide special revelation now that the Scripture has been completed, given as it was through apostles and prophets. Not in any ordinary sense, at least. The foundational work of the doctrine of our faith was done by the apostles (all eyewitnesses of the resurrected Christ).
It is not "added on to," by persons claiming that authority today. Biblically, apostles were all chosen by Christ and were eyewitnesses of Him.
The standard practice of charismatic/pentecostal churches in our era violates this major biblical precept, whether they understand the doctrine behind it or not. Charistmatic/pentecostal in our generation means (incorrectly) seeking revelation through I Cor. 12 gifts especially speaking in unknown tongues and interpretation of unknown tongues as a focus of corporate worship. They are treated (incorrectly again) as an ordinary means of special revelation which they are not now in light of the completed revelation of Scripture.
This violation is one reason there is so much disorder in their communions.
Miracles can and do occur, but that's not the same thing.
I would allow that there may be "extraordinary" occurrences of I Cor. 12 in the revelatory sense, but that's more of a concession to opinion rather than something I can say clearly from Scripture. But it is NOT an ordinary means of revelation today, nor to be a focus of corporate worship because the WORD is that.
Sola scriptura reflects all that.
Romans 12 and Ephesians 4 gifts continue, being non revelatory in the sense of the doctrine of Scripture.
Discussions of this issue often miss the heart of the issue- new revelation and motivational and administrative gifts, and often are posited, incorrectly, on a discussion of whether miracles can still occur (continue).

Of Providence
....
III. God, in His ordinary providence, makes use of means,[10] yet is free to work without,[11] above,[12] and against them,[13] at His pleasure.

The Puritans knew all this, they understood
Sola scriptura, and miracles.
