I need help fixing some issues in a drupal website

- website was migrated and many dates on the posts are now wrong, see if you can return them to the original date. Posts are not being ordered in chronological order. - There is a button "Continue reading..." that should only be shown if there really is more content to read, many times there isn't and the button should appear - search isn't finding everything, it finds some things but some results are missing - there is a page ../content/files that shouldn't be public - The survey isn't working properly and showing the option "see results" before users vote - There is a css issue in one page where boxes of content have a lot of blank space on the bottom because div has fixed height, it should have height = auto - There is one text I can't seem to translate - there is one URL that returns the error "not authorized" - there is a strange function/URL that is the ../tracker, I don't want this active/public - Like Button stopped working: [login to view URL] [Your plan does not allow to load Like button using HTTPS. Upgrade your website plan on [login to view URL]] - embed twitter feed on a page - I want to change the base color of the website
