Before I begin, I was talking with the hosting service and with template´s developer and nobody understands what is happening in my website.
I have multiple domains pointing to the same folder that is where I have installed the website, the problem is that according to the web domain you enter is correct or is deconfigured.
I put it in situation. Install wordpress on my domain http://www.snailbagshop.com and route http://www.snailbag.es and http://www.snailbag.eu to the folder where I have wordpress installed, the problem is that if you run the website in Chorme is correct in all domains, but with Firefox, IE, Safari or Opera, is not correct, menus and letters are disproportionate, if you check http://www.snailbagshop and http://www.snailbag.es you will see the difference in the menu that is on the slider.
It is not really where to ask, after searching the forum, ask the hosting provider and developer of the template (do not give me solution), I thought I contact you.
I hope someone help me, any information do not hesitate to ask me require.
Thanks in advance
