error page

Double Dividend recently  (1/5/2018) added an article on the symbol AMZA.... I added comment  to it ....MY bell notification at the top of my page later  claimed that other comments were added... I went from there to read those comments and I get your error page ... that has happened twice now that I have been notified of new comments and I cannot get there as I keep getting the error page even after reloading several times.... I went to the authors info page and clicked on the  AMZA  symbol for articles he has authored it says two  but yet only one old article comes up the new article does not appear there either...
