Developed the project and at some point he stopped compiling. Since the studio does not write humanly, what exactly is an error in its opinion, just rolled back - deleted the added pages. But after that, the code nevertheless does not want to compile, displays errors that say that, in the studio’s opinion, the deleted pages are still alive somewhere else. Search ran through the contents of the project - nowhere information on the remote page (activit) is not found. Tell me how to tame this wild horse 
vOptions was an activation that I deleted. She is not searching anywhere. I rebuilt the project, cleaned the bin folder - it's useless.
