**List of steps to reproduce** (step by step, including full links if applicable):
* Click on a random Wikipedia article, a big, detailed one, like "Russia" or "Fumio Kishida" for examples.
* The article appears normally
* But there is no sign of the table of contents at the beginning of the article
* It is not related to the "Hide" function of the template, the template simply is not there
**What happens?**:
The table of contents on some, but not all, Wikipedia articles (and when I say some articles, it is articles who should have it and had it until then) is no longer there
**What should have happened instead?**:
The table should be there, or at least the reduced part of the table with the "show" table function.
**Software version (if not a Wikimedia wiki), browser information, screenshots, other information, etc**:
