I read the "Info or Zoom Control Has Bad Shape"
I tried the first method and the zoom showed up but the placement of the zoom control is not in the correct place. See image called chrome.png. I also have the same problem in Safari as Chrome. I didn't try the second method because this map is a plugin. I also tried the third method but it had the same results as the first method. Nothing worked in FireFox. No matter what i tried nothing fixed it.
if you open your page, you'll see that exists
in your code.
I suggest you use method 3 in my docs - set CSS class for map div, after that open your template file (you can see, it exists = template.css), and add at the end of that file your definition for map div class with !important too. That overrides style in map div, and all will be fine.
You can try - open page, find zoom image, and by developer tools remove max-width style, and you'll see correct zoom image
