Autoembeds problem on 3.5.x (Multi-site install upgraded from old MU)

  • After upgrading to 3.5.1, autoembeds (i.e. one line of a youtube video without any formatting or extraneous spacing) appear to be broken on all themes on a multi-site installation that was upgraded years ago from WordPress MU. Troubleshooting includes disabling all plugins, replacing all core files, testing with the latest themes but to no avail.

    Themes including a smattering of default “packaged” Twenty 10, 11, 12 – and custom themes that don’t utilize any plugins all yield the same result with all plugins disabled on sites that previously displayed the YouTube automatically embedded links and various “the_content” filters have been applied or removed to see if formatting changes leading to the conclusion that 3.5.1 may have possibly made a change that only affects multi-site installations (or possibly just a subset that originally used the old MU platform).

    Any thoughts?

    This appears to have something to do with the way that the oembed call is made as we see the postmeta references but instead of having the expected iframe… lines they have {{unknown}} for valid https://www.youtube.com/watch?v= links

    Have you resolve your problem. Looks like I have the same problem with you. Sometimes it works, but now it won’t

    Unfortunately we weren’t able to identify the cause of the issue but it looks like when WordPress creates the meta post entry, it may have something to do with the oembed call out to WordPress to grab the embed code (since we see the oembed row created but with “unknown” instead of with the expected iFrame attributes). At this time we can only assume that it affects a very limited number of installs and our thought is that it may have something to do with the server configuration itself rather than WordPress given that it used to work before moving to a Plesk 11 platform. Are you running a control panel of some sort?

    Control panel? do you mean something like cpanel? I’m using shared hosting with cpanel. wp configuration on my site is very basic:

    wp 3.5.1 (local version id-ID) with wp total cache, disqus and better wp security plugin. Before it I was using facebook social plugin, but it’s too hard to configure and I deleted it already. I’m not really tech savvy.

    Thing that I change in wp-config before installation are salts and DB table prefix.

    Now even with iframe, youtube video won’t show up. Looks like there are others who have the same problem, but if not everyone experience this, then probably there will be no fix in the next wp update.

    If this because the configuration on my site, I really like to know what is it and how to fix it.
