Rewrite OK!
In modx, it seemed normal to work with subdomains

codex.wordpress.org/%D0%A1%D0%BE%D0%B7%D0%B4%D0%B0... try this.

Answer 3

It is possible to write in Django. The code base is the same, only the settings file changes. Well and accordingly the database at everyone the. And so new chips will roll quickly, they made a change to the template and immediately on all sites.

Answer 4

I don’t really like Drupal, but I made the site www.msk.arbitr.ru and more than three dozen similar sites on it from one engine (for example, www.samara.arbitr.ru ) and I note that it copes well with the task. Updates began to take not a week, but several hours, the rollout of new features was also greatly simplified and accelerated.

Answer 5

Try OpenCart for an online store in the settings, you can create dozens/hundreds of online stores on one engine

Answer 6

Well, then it's not crm, but cms )) For such monsters, which you cited as an example, all sites are spinning on self-written engines. Moreover, you have non-standard content: IM plus various modules. None of the existing on the market will give you such functionality. Better for the money that you would have spent, hire a specialist and make an adequate system for routing pages and modules. Plus, the load can go due to incorrect optimization of database queries, and if it is one for all N domains, then it’s generally easy.
And the phrase "each new feature is updated on all 33 sites, loads the server" is still not entirely clear.
