I have a strange issue where any page that contains the word update will not save, nor can you preview. If you click save or preview the edit page is reloaded.
MediaWiki 1.29, PHP 7.0 and Maria DB 10.1.29

Also if it contains the word "from". Seems like its having an issue with some sql command words?
Is your wiki public? If so, can you point to it?|
If not, which extensions do you have installed?
oh, and does the word "select" cause a problem?
This is a typical problem with ModSecurity. Ask your hosting provider.
