Errors aren't important. Most important are completions and definitions.
Is there a way to fix it??
Michael asked you to show code. He can't guess what's going wrong. I
suggest that either
- you send (a portion of) your project to Michael, together with an
example of what goes wrong. So he can check wether the problem is
reproducable, and if so, try to fix it.
- you try to isolate the problem yourselves.
It could of course be that errors hinders parsing thus breaking code
completion.
