Editor shows at [code] wrong results

Hi there,

I have the SythaxHightlighter plugin on my site, which works wonderfully.

I also use a theme with the Visual Composer, where a code fragment is integrated via the editor.

But the problem now: If I integrate the code and want to edit it again, the editor changes my code. Here’s an example.

After changing and saving again, the editor changes the “"” ind a quotation mark “.
But that shouldn’t happen.

That’s how it should be: Include=” “SpaProxyServer”: {” />
This is how it is after editing and saving the code again: Include=” “;SpaProxyServer&”: {” />

Do you have a solution so that my editor doesn’t change this?
I’ve tried many things, but nothing worked. The editor keeps changing this for me and I don’t know what to do anymore.

Many thanks for your help!
