PHP Storm marking class attributes in paragraphs
In one of my projects, phpstorm marks all paragraph class attributes as follows

I have tried a simple file with only one <p class = 'dog'>Dog</p> and the problem exists.
Mousing over the error brings up a dialog saying something like "No data sources are configured to run this SQL and provide advanced code assistance
Only happens in one project so I'm thinking it is a setting somewhere.
Thanks,
Dave.

Hi there,
Place caret in such problematic place and invoke Alt+Enter (or via light bulb icon). Show what menu do you see.
At the same time: post screenshot of "Settings/Preferences | Editor | Language Injections" -- I'm interested in any entries except "Built-in" in last column.
Tow items in the menu
Thanks
Dave
Delete 3rd rule from the bottom -- the one that named "xml:p/@class" and has "IDE" in last column.
You have accidentally created such rule .. and now SQL gets injected into class="" (everything inside it is treated as SQL fragment)
I figured that out after your previous message and thought I had responded to you.
I have absolutely no idea how that rule was created but I'll know where to look if I have this problem in the future.
Thanks,
Dave
