I am using MediaElementJS on my site and some IE9 users are seeing a warning from the browser which says "Silverlight was blocked because it is out of date and needs to be updated".
I really don't want any users to see this message, but even if I remove silverlight from the plugins list when I initialise MediaElementJS so that it won't try to use it, the users still see the warning.
Is there something I can do to force MediaElementJS to not try to use Silverlight at all so that the warning does not appear?
Or any other solution to suppress this warning?
Thanks, P

I am helping out with a site built using DNN (DotNetNuke). A certain set of pages are somehow blocking the browser's back button. We don't want this behavior. How do we re-enable it? I suspect there's a setting somewhere that's gotten turned on accidentally, but I haven't been able to find any reference to that in the documentation.
I'm not aware of such a setting. It might be in your theme (skin), possibly in some javascript.
I am working on a site: greatlakesecho.org When I try to edit a post, the content just disappears from the visual editor. I am running the latest version of Word Press but this happened on the previous version as well. I am using the Project Largo theme with the site.
The site was recently migrated from to a new host and has gone an overhaul into a responsive design. This first started happening when I changed the character encoding to remove odd symbols from the posts. I was successful in that by changing it to utf16. At this point only older posts that were created before the migration would disappear when I clicked edit. I have since updated to the latest version of Word Press and it happens to every post.
I've already made sure the wp-config has the correct encoding.
It happens with all themes.
Tried deactivating all plugins.
I also see this when enabling debuggin:
WordPress database error: [Table 'greatlak_wp776.wp_itsec_lockouts' doesn't exist]
SELECT lockout_host FROM wp_itsec_lockouts WHERE lockout_active=1 AND lockout_expire_gmt > '2014-04-22 19:52:36' AND lockout_host='35.9.132.246';
WordPress database error: [Table 'greatlak_wp776.wp_itsec_lockouts' doesn't exist]
SELECT lockout_user FROM wp_itsec_lockouts WHERE lockout_active=1 AND lockout_expire_gmt > '2014-04-22 19:52:36' AND lockout_user=93;
edit: Extra Info
Wordpress has this documented on their documentation. It can be found here, of course you will be converting to utf16 instead of utf8. http://codex.wordpress.org/Converting_Database_Character_Sets
Check your wp-config file's encoding, make sure it's set to utf-16
Activate a new theme, see if that still happens. If so, it was a theme issue.
Deactivate all plugins, see if it still happens. If so, reactivate 1 by 1 and see when it happens again.
Also, check your browsers console for any errors
I had to remove the Navis Media Credit plugin manually. I searched through the plugins folder using WinSCP and apparently when I was removing all the plugins using the WordPress admin panel, this one wasn't actually getting removed. This plugin was conflicting with the theme I am using and I learned this by deleting all the plugins and using one of the default WP themes.
It may be a Chrome Extension. Here is what I experienced...
In Chrome - a Wordpress site loads the Add New Post screen which appears to get overwritten - this happens after typing a few characters (not immediately) in the title or body. Updated theme, removed plugins, no change. At one stage noticed a bug in html2canvas.js but now cannot reproduce.
Tested in Firefox, works fine.
Traced to a Chrome Extension - Screen Shader - F.lux for Chrome 1.7.720 - one that removes BLUE from Chrome display (for night work). It probably does use use html2canvas. When it is deactivated, Chrome again behaves normally. Tried with another plugin "Blue Light Filter Guard" - not as well featured - but it does not trigger the bug.
May not be the same as your problem, but try in Firefox and check your Chrome Extensions.
I have a website running on dotnetnuke. However, recently I can't do any action (edit content or page setting) on certain pages (the products subpges in www.midoco.com). Does anybody know why this happen?
What version of DotNetNuke are you on? Check the HOST SETTINGS page to see if you are using the HOSTED Jquery option, if so, try disabling that option.
It is probably a javascript issue, try firing up chrome developer tools (hit F12 in chrome) and check if you have a red X in the bottom right corner. If so, click it and check what causes the issue. I had some similar issues caused by single quotes insted of apostrophes in a language pack and spent a lot of time to find the issue. I just went to one of the pages and see you have an error in /engine1/script.js in your skin.
I have a small silverlight app and when I "play" it, it just hangs in the browser. (Shows the spinner).
How can I debug this and find the cause?
Thanks
I would recommend the following...
Use Fiddler to see if there is any data that is coming/going to the server when you use this application.
Use another browser and see if the issue manifests itself
If it happens with all the browsers, then you can try capturing a dump of Internet Explorer and try to analyze it for the actual issue.
Is there a javascript exception? Open up the developer tools for your browser (F12 in IE and Chrome) to see the specific error message and error code. Once you have those, google them and voila!
I was reading this post and noticed that when I am closing browser or tab the message is showing as well. I need to disable the Refresh button or give some warning but problem with solution in that post is that it shows message when I close browser.
Is there any way to show message only on refresh?
I know that there are some posts like this on stackoverflow.com, but none of them work for me. So this is not a duplicate question unless there is a working solution.
window.onbeforeunload from JavaScript (as noted in the post you link to) really is the only way this can be done in a cross-browser, cross-platform way, that I know of.
But that does end up getting triggered for F5. That's just the way browsers work - they unload a page before reloading it, even in the refresh case.
Do you really find users hit F5 often enough for such a prompt to be a problem?
Isn't it possible to catch a key down event on F5?
If not with silverlight you can probably with a keyboard hook.
