Router Shows Forbidden Page and then Change it to OK 200 Response (maybe a BUG)

Update!


I think this is a BUG and source is Wix’s codes not mine. I tried it for more times without any changes and sometimes I don’t get this 403 page and sometimes I get it.

When I don’t get 403 page there are no errors on console.
When I get 403 page there are some errors related to Wix’s codes. About site info as I understand.

(I don’t use AdBlock)

So anyone from Wix can help me about this why I have this errors do I need to do something about this?
