 * Dear all, trying to fix some problems of WPGMaps plugin moderator highlight that
   some problems come from Google Language Translator. Herewith find all the analysis:
 * > Hi Maurizio
   >  I appreciate what you are saying completely, and I’m very sorry
   > for any inconvenience caused, genuinely, I’m very sorry to be the bearer of
   > bad news but I can categorically state that a JavaScript error in their code
   > is causing the map to break. Please allow me to explain how the flow of execution
   > works on a page load. Firstly, script tags are loaded and parsed, in the order
   > they appear in the document. Any code in these script tags is executed immediately
   > after the script has been loaded and parsed. Sometimes, it’s desirable to wait
   > for all scripts to load before executing code, rather than executing immediately.
   > This can be achieved by listening for the “document ready” event, which is 
   > usually done using jQuery. These listeners are bound immediately, when the 
   > script loads. Once all the scripts have loaded, jQuery fires the “ready” event,
   > and each listener that bound to this event is called, in the order that they
   > were bound in. If one of these listeners causes an error, execution will halt.
   > When execution halts, no further listeners will be called. So, if plugin A 
   > binds a ready listener, then plugin B binds a ready listener, when the ready
   > event fires, if plugin A’s listener causes a JavaScript error, then the ready
   > event will not fire for plugin B. When I look at my console on your site, I
   > can see this error: Uncaught TypeError: $(…).toolbar is not a function at HTMLDocument.
   > <anonymous> (scripts.js:59) at i (jquery.js:2) at Object.add [as done] (jquery.
   > js:2) at a.fn.init.n.fn.ready (jquery.js:2) at scripts.js:58 From this line:
   > at a.fn.init.n.fn.ready (jquery.js:2) We can see that this is during the jQuery
   > ready event. From the top of the stack trace, you can see that the file scripts.
   > js is causing this error on line 59. If you look at the full URL for scripts.
   > js, you will see that is [http://www.ferentino.org/wp-content/plugins/google-language-translator/js/scripts.js](http://www.ferentino.org/wp-content/plugins/google-language-translator/js/scripts.js)
   > See google-language-translator in that path for the name of the plugin causing
   > this error. This error is triggered by the Google Language Translator plugin
   > trying to call a function named toolbar when no such function exists. When 
   > an error happens, execution halts, and the ready event will not be triggered
   > for any JavaScript listeners that were bound after Google Language Translator
   > loaded and bound this listener. Please see my first attachment showing the 
   > stack trace for this error. Please see my second attachment showing the file
   > [http://www.ferentino.org/wp-content/plugins/google-language-translator/js/scripts.js](http://www.ferentino.org/wp-content/plugins/google-language-translator/js/scripts.js),
   > where this error originates from. I can use the live source edit and source
   > overrides to remove this in my development environment, without modifying the
   > file on the server. Please see my third attachment for the overriden file, 
   > in which I have commented (effectively removed) the code causing this error.
   > If I do that, then reload the page, that code is not run, so the ready event
   > is not interrupted, the flow of execution continues, the ready event listener
   > fires for our plugin code, and the map is displayed and fully functional, as
   > you can see in my fourth attachment. I’m very sorry for any inconvenience caused,
   > I appreciate that this can seem befuddling, we do put out at lot of updates
   > as we are constantly working to improve the product and it’s compatibility 
   > with other plugins. I really don’t wish to pass the buck so to speak, but I’m
   > afraid that I can state without any doubt whatsoever that is caused by the 
   > Google Language Translator plugin trying to call toolbar when no such function
   > exists. We would be unable to advise you on a fix for this as this pertains
   > to their code. I can advise you that removing this code will solve the problem,
   > as you can see above, however as I’m not familiar with their code, I can’t 
   > advise you on what the deeper consequences of removing that code might be. 
   > You would need to ask the plugin author about this, firstly I would ask them
   > why their code is failing here, and secondly if they’re unable to advise on
   > a fix, I would ask if it’s safe to remove this code. I would also advise that
   > this error will stop the ready event from firing for all plugins that subsequently
   > bound the listener, not just WP Google Maps, so in any case, I would advise
   > that you take this up with them to get this solved as this will likely cause
   > problems with other plugins too. I really hope that makes sense. We do strive
   > to be as compatible as possible with other plugins, of which there is a myriad
   > of combinations and configurations, but I’m afraid that in this instance because
   > their code stops our from executing at all, you would either need to remove
   > that or speak to them. We would be quite happy to facilitate that if it would
   > help. I hope that makes sense and is of some help? Kind regards – Perry Attachments:
