Comments on: Opera hanging on page load on your site? Check for missing files. http://frankkoehl.com/2009/04/opera-hanging-page-load/ The more you know, the more you don't know Tue, 15 May 2012 23:58:36 +0000 hourly 1 http://wordpress.org/?v=3.3.2 By: Zak http://frankkoehl.com/2009/04/opera-hanging-page-load/comment-page-1/#comment-3878 Zak Sun, 25 Sep 2011 09:09:16 +0000 http://frankkoehl.com/?p=490#comment-3878 I know this is resurrecting a *very* old issue, but I'm still getting the same thing in Opera 11.51 (and a preview of 12.00) in September 2011. The classic trigger to reproduce the hanging is loading a page with a google-analytics javascript element in it. My router redirects calls to www.google-analytics.com to 127.0.0.1, so it seems that Opera is waiting to find 127.0.0.1/ga.js before rendering the rest of the page. Viewing source, removing the GA script and Applying changes allows the page to load fine. Interestingly, Dragonfly doesn't show a body tag in the page details, just html and head. View source shows the whole page. I don't know enough about Dragonfly to know whether that's useful info or not. Anyway, I thought I'd put this here in case anyone else Googling for the same problem stumbles across this page too.

Thank God my mother adviced to try to take the <a href="http://bestfinance-blog.com/topics/credit-loans" rel="nofollow">credit loans</a> at banks. So, I acted so and was satisfied with my short term loan. Some time before, I needed to buy a car for my organization but I did not earn enough cash and could not order anything.

I normally don't go to others for news. I cannot make it load videos either. Withe the same sites and computer (double booting), IE works well. I've been chasing this for about 5 days now. Sure would appreciate some ideas. Currently using Ubuntu Lucid Lynx, fully updated. The problem may be in the site because I did a validate with opera and it came back with about 300 errors for foxnews.com. I didn't check cnn. Primarily it hangs on foxnews.com and cnn.com.

Steen Fri, 08 May 2009 21:39:05 +0000 http://frankkoehl.com/?p=490#comment-1120 In response to Tim's comment above: right now the footballsfuture.com link works just fine here. The rotoworld.com one does however show a problem. It's caused by some ad-script, and from some very superficial debugging the problem is that the script http://media.fastclick.net/w/get.media?sid=49081&m=6&tp=8&d=j&t=s gets added to the document over and over. The server seems to redirect back to the script that inserted it in the first place, so it gets inserted again. Right now it looks like a server error but I'll try to verify that.. Frank: sorry to hear you couldn't find the problem anymore, I thought it might be some elusive corner case issue. If you see it again do let me know.

Browser aside, responsive support to user complaints definitely separates Opera from the pack a bit. I am in the process of putting together a page that replicates the problem I was having. Unfortunately I didn't write down exactly which file was causing the issue, and am currently unable to reproduce the error. This leads me to believe that the script load order, in-file location (head vs. elsewhere), and/or caching may have something to do with the issue. Will post if I uncover the bug again.

It doesn't happen on IE or anything like that as mentioned, and its very frustrating. I have the same problem, and here are the two sites i have the problem with.

Steen Mon, 27 Apr 2009 19:15:21 +0000 http://frankkoehl.com/?p=490#comment-1026 Hi, I'm Hallvord and work for Opera on JavaScript quality assurance and testing. Thanks for the blog post, what you're describing sounds like a bug. Opera is meant to report missing script files in the error console - you should have seen a message saying "Warning: could not load http://www.example.com/script.js". The page should never be non-interactive, and the loading indication should go away. My guess is that it might be something about the page's state at the point the missing script is meant to load that triggers the bug. For example, if the script is inserted through the DOM or fails to load during heavy DOM manipulation, or if there is some error with HTTP pipelining that makes Opera believe the script is in fact on its way. It's however impossible to pinpoint the reason without seeing the actual failure, so if you could contact me and point me to the page you had problems with and tell me what script was missing - for example by filling out the form on bugs.opera.com/wizard and refer to your blog post - I'll follow up and make sure this bug no longer is a stumbling stone on our way to markets and profit :-) Hi, I’m Hallvord and work for Opera on JavaScript quality assurance and testing.
