Hi Folks,

I did some digging and found that this plugin (YouTube SimpleGallery @ https://wordpress.org/plugins/youtube-simplegallery/) is broken on two levels:

1. The format of the YouTube oEmbed code has apparently changed
2. The YouTube has deprecated its v2 API, which this plugin uses

So, unfortunately for the people wanting a „code clean“ solution (from the following thread https://wordpress.org/support/topic/just-broke-shows-only-first-video), there is none. Also unfortunately but for everybody (including me), this plugin is dead, the last update is almost 2 years old. However I like the simple building of galleries very much, so I had to fix the plugin. Keep in mind that the fix is quick and dirty, apply on your own risk.

I tried to do the fix the right way but I was not able to disable the automatic use of oEmbed for YouTube. Maybe, sometime in the future I will return to this code and make my first plugin the right way. But for now, here is what you need to do this:

[youtubegallery]
vAJFM9qZlrI
qnRJ5Z-HP3E
BZ3Xc7bG10U
WBq_jNgpSYE
[/youtubegallery]

instead of this:

[youtubegallery]
http : // youtu . be/vAJFM9qZlrI
http : // youtu . be/qnRJ5Z-HP3E
http : // youtu . be/BZ3Xc7bG10U
http : // youtu . be/WBq_jNgpSYE
[/youtubegallery]

I don’t really like this (as I have to edit several pages on my other blog) but parsing that mess of an HTML returned by the oEmbed was beyond my PHP/Wordpress skills. So put the video IDs only, one on a line.

Then apply the following patch (using git or any other way you prefer): http://blog.pvalley.info/wp-content/uploads/2015/05/0001-Fixed-the-youtube-gallery.patch. But before that read the notes under the patch text as they are important.

You will need to disable Timthumb, as it is not working. I haven’t had the time to investigate the issue. Also be aware that this patch is breaking the Vimeo support and that it is only fixing the youtubegallery, to the youtubeuserfeed shortcode. Finally you will need an YouTube API key. It should be put here:

FIXME: add your API key here.

And at the end, a word of warning. Use on your own risk.

I hope this helps.
