Error in MIME type-- can't display SVG figure

Dear Forum
I worked on some webapp on Mac OS X and now transfered it to a Linux server. At one point, some mathematical function is evaluated and a resulting graph is generated using GNUPlot in SVG format. The app is started by Apache. However, the Mac and Linux Apache lead to slightly different SVG's. Only the Mac SVG displays in the browser, the SVG from Linux does not display in the browser. Here are the headers of both SVG files, I believe it's what controls this behavior.
Mac SVG:

Code:

<?xml version="1.0" encoding="utf-8"  standalone="no"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" 
 "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
<svg width="600" height="480" viewBox="0 0 600 480"
 xmlns="http://www.w3.org/2000/svg"
 xmlns:xlink="http://www.w3.org/1999/xlink">
<desc>Produced by GNUPLOT 4.2 patchlevel 5  </desc>

<defs>

	<circle id='gpDot' r='0.5' stroke-width='0.5'/>
	<path id='gpPt0' stroke-width='0.222' stroke='currentColor' d='M-1,0 h2 M0,-1 v2'/>
	<path id='gpPt1' stroke-width='0.222' stroke='currentColor' d='M-1,-1 L1,1 M1,-1 L-1,1'/>
	<path id='gpPt2' stroke-width='0.222' stroke='currentColor' d='M-1,0 L1,0 M0,-1 L0,1 M-1,-1 L1,1 M-1,1 L1,-1'/>
	<rect id='gpPt3' stroke-width='0.222' stroke='currentColor' x='-1' y='-1' width='2' height='2'/>
...

And Linux SVG:

Code:

<?xml version="1.0" standalone="no"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 20001102//EN" "svg-20001102.dtd">
<svg width="600" height="480" viewBox="0 0 600 480"
 xmlns:xlink="http://www.w3.org/1999/xlink">
<desc>Produced by GNUPLOT 4.0 patchlevel 0 </desc>

<defs>


	<circle id='gpDot' r='1'/>
	<path id='gpPt0' style='stroke-width:0.222' d='M-1,0 h2 M0,-1 v2'/>
	<path id='gpPt1' style='stroke-width:0.222' d='M-1,-1 L1,1 M1,-1 L-1,1'/>
	<path id='gpPt2' style='stroke-width:0.222' d='M-1,0 L1,0 M0,-1 L0,1 M-1,-1 L1,1 M-1,1 L1,-1'/>

	<rect id='gpPt3' style='stroke-width:0.222' x='-1' y='-1' width='2' height='2'/>
...

Is this encoding attribute the reason why it does not display? How do I get Apache under Linux to print this attribute into the SVG file?

Thanks for any hints.

You can test this by editing a copy of the file and adding it. Unless your svg file has UTF-8 characters in it, it won't make a difference. I tried both your xml version lines on an svg file on my system and both displayed fine in FF8. What browser are you using? Very old ones don't support svg.

Thanks, I was using Firefox as well. I'll be looking at your suggestion.

Also, could be some other reason it doesn't display. Test the svg directly using "Open File" menu and have the error console up in Tools -> Web Developer.
