Replace \cal by \mathcal. You may also edit the template to replace:

\usepackage{mathptm}

by:

\usepackage{mathptmx}
                    ^

This will produce a more cursive E.

As to why {\cal E} works in LaTeX Equation Editor but not in Equation 
Service, the difference lies in the templates (preamble in LaTeX 
Equation Editor jargon):

- The basemathmode template in Equation Service uses: 
\documentclass{minimal}

- The default preamble in LaTeX Equation Editor uses: 
\documentclass{article}

\cal is a deprecated La	TeX 2.09 command, to be replaced by \mathcal in 
LaTeX 2e (beware, too, that \cal is a declaration while \mathcal is a 
command taking an argument). For backward compatibility the article 
class defines a command \cal:

\DeclareRobustCommand*\cal{\@fontswitch\relax\mathcal}

This definition is absent from the minimal class, yielding "ordinary" 
uppercase letters instead.

You may use the Edit button in Equation Service to edit the 
basemathmode template yourself (replacing minimal by article), and 
you'll see the output change on a new Typeset.
