[TYPO3] error message after installation of css_styled_content

[tapio]

> Warning: exec() has been disabled for security reasons in

you might have enabled ImageMagick. It can't work if exec() function has 
been disable. stdgraphic - graphics. This doesn't relate as such with
css_styled_content. You have just defined such TS templates, which need 
such graphic tasks, which your server provider doesn't allow you to 
execute.

Check if
$TYPO3_CONF_VARS["GFX"]["im"] = '1'; in your localconf.php

In your case it *must* be
$TYPO3_CONF_VARS["GFX"]["im"] = '0';
