Wow, I just discovered that with the new login system, if you log out in a different tab and log back in, then submit a thread comment, your comment vanishes without an error message. Thanks Wikia.

So, ReapTheChaos, the short version:

If you're talking about the "New Visual Editor", Wikia Staff will disable it as the default for anons, but it will still be available in the drop down menu, and for people who have set it in their preferences. Unfortunately, they retired the "use site default" option long ago.

Write in to Special:Contact/general with specific diff links or step-by-step instructions of how the New Visual Editor is causing problems. Also include the diff links of the things you have to fix.

Ask them to set the old editor as default until the problem is fixed. Since they appear to have abandoned development of the New Visual Editor, this practically means "forever".

If you're talking about the old "visual mode" rich text editor which shows the "visual" and "source" tabs, then you can use __NOWYSIWYG__ on individual pages to disable it. Or write in to staff with specific problems and ask them to disable it for the whole wiki. (I've never done this, so it might not work.)
