An unwanted jQuery UI file. I'm downloading it without calling it

[lsag]

Hello. i have a very weird error in jQuery. this is the message in chrome's console:

GET http://localhost/clientes/promundi/site/v4_pw/site/en/contact/images/ui-bg_glass_100_f6f6f6_1x400.png 404 (Page Not Found) jquery-1.11.1.min.js:2

GET http://localhost/clientes/promundi/site/v4_pw/site/en/contact/images/ui-bg_gloss-wave_35_f6a828_500x100.png 404 (Page Not Found) jquery-1.11.1.min.js:2

GET http://localhost/clientes/promundi/site/v4_pw/site/en/contact/images/ui-bg_highlight-soft_100_eeeeee_1x100.png 404 (Page Not Found) 

i can see jQuery is being loaded properly, because this works, showing the expected alert box. But what on earth are those files? And "ui-bg_glass" seems to be a jQueryUI file, which i'm not using! 

<script type="text/javascript">

          $(document).ready(function($){

              alert("message");

          });

</script>

and i'm not calling other jquery scripts. it happens with any version i try to run (one at a time, of course)

calling 2.1.1 with the CDN

<script src="//code.jquery.com/jquery-2.1.1.min.js"></script>

calling 1.11.0 with the CDN

<script src="//code.jquery.com/jquery-1.11.0.min.js"></script>

calling 1.11.1 locally

<script src="http://localhost/clientes/promundi/site/v4_pw/site/site/templates/promundi/js/jquery-1.11.1.min.js"></script>

calling 2.1.1 locally

<script src="http://localhost/clientes/promundi/site/v4_pw/site/site/templates/promundi/js/jquery-2.1.1.min.js"></script>

I'm not sure if this is a processwire issue, but i don't know where else to look for

any ideas?

i have tagged this with carrousel and slideshow, because that was the initial problem i had. But while debugging, i'v seen that even the simplest jQuery is affected. And then forgot to remove the tags

So the resolution was: create a new barebones page, and line by line add the code again. I have no idea of what was the cause, but its working
