Bizarre Error in Chrome Developer Console - Failed to load resource net ERR CACHE MISS

Question

As far as I can tell  this error was not being thrown yesterday on Chrome  and as of this morning  it is  I have not changed any of my browser settings  I have attached a screenshot  after opening closing Developer Tools window four times      This issue is tangentially similar to Stack Overlow post Failed to load resource under Chrome except that it only occurs when I  Inspect Element  in Chrome  Here are the details I have   To the best of my ability I undid everything I did since last night  when I did not have this error  and the error persists  When I remove all pre- lt html gt  PHP code  the error disappears   When I only remove all the pre- lt html gt  PHP code except    lt  php session start      gt    the error returns   Since the error seems to involve PHP  I checked my error log  but there are no notices  warnings  nor errors  When I close the Developer Tools window and then open up the window without a page reload  the number of errors increments by one each time   When I keep the window open  and then reload the page  the page reloads without throwing the error  However  as soon as I close the Developer tools window again  then open it  no page reload   the error is thrown  I checked my site on Firefox with Firebug enabled  and no errors are thrown  making it seem like a Chrome issue  version 38   My site seems to function normally otherwise  Other sites on device browsed via Chrome  for example  Yahoo  also experience this error   Also  I have not manually changed any of my browser settings since months ago  As an additional note  this is the second strange error I have encountered in Chrome in the last year  see Stack Overflow question Failed to load resource  net  ERR NETWORK IO SUSPENDED   to which no one was able to find a solution  even with a bounty offered   Is there a way to prevent this error  or is this a browser-only issue  On a side note  when I open up Developer Tools in Chrome for Stack nbsp Overflow  there is no error thrown  so either Stack nbsp Overflow is not coded in PHP or they have a way to prevent this error  I think my site is not affected  but I am not 100  sure  and it makes me nervous

On Chrome s latest update  38 0 2125 104 m at the moment   Google added the option to know whether the files loaded to the website were newly downloaded from the server - or read from the local cache   When an error like yours  hits  the console - you know the files were just downloaded from the server and not read from the local cache  You can recreate this error by clicking Ctrl   F5  refresh and erase cache    It fits your description where Firebug  or equivalents  doesn t fire any errors to the console - whilst Chrome does   So  the bottom line is - your re just fine and you can ignore this error - it s merely an indicator

See if you can recreate the issue in an Incognito tab  If you find that the problem no longer occurs then I would recommend you go through your extensions  perhaps disabling them one at a time  This is commonly the cause as touched on by Nikola

Check for the presence of words like  ad    banner  or  popup  within your file  I removed these and it worked  Based on this post here  Failed to load resource under Chrome it seems like Ad Block Plus was the culprit in my case
