Can anyone tell me what does those +something+ means?

Well, not sure yet but according to this you're not the only one (note the almost identical ip!).

After a bit more digging I found several code snippets like this:

Code:

  $content .= "var ptnURL=ct+'de.trendmicro-europe.com/support/pattern.php'\n";

This seems part of a "TrendMicro Virus Info Feed" script. So my guess is somebody found a bug in it and is scanning for it.

What was the source of the error?
