Problem with <em> and <strong>

Hi

Again, sorry for taking so long to reply.
In modules/fckeditor/fckeditor.config.js you can add a part of the original config modules/fckeditor/fckeditor/fckconfig.js adjusted to your needs:

// Do not add, rename or remove styles here. Only apply definition changes.
FCKConfig.CoreStyles = 
{
	// Basic Inline Styles.
	'Bold'			: { Element : 'strong' },
	'Italic'		: { Element : 'em' },
	'Underline'		: { Element : 'u' },
	'StrikeThrough'	: { Element : 'strike' },
	'Subscript'		: { Element : 'sub' },
	'Superscript'	: { Element : 'sup' },
	
	// Basic Block Styles (Font Format Combo).
	'p'				: { Element : 'p' },
	'div'			: { Element : 'div' },
	'pre'			: { Element : 'pre' },
	'address'		: { Element : 'address' },
	'h1'			: { Element : 'h1' },
	'h2'			: { Element : 'h2' },
	'h3'			: { Element : 'h3' },
	'h4'			: { Element : 'h4' },
	'h5'			: { Element : 'h5' },
	'h6'			: { Element : 'h6' },
	
	// Other formatting features.
	'FontFace' : 
	{ 
		Element		: 'span', 
		Styles		: { 'font-family' : '#("Font")' }, 
		Overrides	: [ { Element : 'font', Attributes : { 'face' : null } } ]
	},
	
	'Size' :
	{ 
		Element		: 'span', 
		Styles		: { 'font-size' : '#("Size","fontSize")' }, 
		Overrides	: [ { Element : 'font', Attributes : { 'size' : null } } ]
	},
	
	'Color' :
	{ 
		Element		: 'span', 
		Styles		: { 'color' : '#("Color","color")' }, 
		Overrides	: [ { Element : 'font', Attributes : { 'color' : null } } ]
	},
	
	'BackColor'		: { Element : 'span', Styles : { 'background-color' : '#("Color","color")' } }
};

Note: the first two declarations of Bold and Italic had changed (this instruction is valid for FCKeditor 2.5, does not work with FCKeditor 2.4).
Make sure you have cleared your browser's cache (or even restarted it) if you don't see any changes.
