------Solution--------------------
Error_reporting (E_all & ~e_notice); This sentence adds to the controller.php to see the line. Try.

Add in PHP at the beginning, and then the controller.php reported 56 line error, no longer is 55 lines.
I am php idiot, this set of OpenCart program is used in easyphp, and now moved to resin, the root directory is not equipped with php.ini information, Web. XML does not reference the php.ini file, does it matter?

------Solution--------------------
Setting the error level
------Solution--------------------
See if it's illegal to access the class's protected (protected) class variable or class method oh
