So I Know this problem was solved 7 years ago but it's the top result on google so I wanted to add what the solution to my problem.

Under Settings -> Preferences... -> Languages

I had stupidly disabled python without realizing that that's what I was doing, just had to put it back into available items.

Answer 4

Go to Settings -> Style configurator... then disable Enable global foreground color and Enable global background color. This fixed my problem.

Answer 5

You could try going to Language > H > Html and that should highlight stuff.

I had the exact same problem and none of the posted solutions worked for me so I digged deeper and found that I mistakenly assigned my user defined extensions twice under Settings → Style Configurator, for example SQL and XML.

Deleting my user defined extension from one language restored the syntax highlighting.
