 * Hello guys,
    I’ve spent a couple og hours in finding the answer but still don’t
   succeed.
 * we’re developing the theme for our client. He will sell that on the Themeforest.
 * He tests the theme on localhost and today he faced the issue of following warnings
   [http://prntscr.com/6yywax](http://prntscr.com/6yywax)
 * * We’re completely not able to reproduce that on our machines in our office (
   we’re in different countries with our client).
    * He says warnings occur with
   our theme only, other themes work fine. So, the firewall, proxy and other infrastructure
   options don’t seem the reason * He says warning occur on both his local machines*
   He uses 4.2.1, but the issue occur on the 4.1.1 also. We had 4.1.1, updated to
   4.2.1 and still don’t see anything wrong * He usee xamp, php 5.5. We tried to
   reproduce on php 5.5 also, but no result
 * Could you at least give a piece of advice in what direction should we investigate?
   How can we reproduce that issue on our machines?
 * Any help will be great, we’re completely frustrated by this issue.
 * thanks in advance.
