it's easy to check. Disable 'OEmbed' plugin and enable 'Elgg Hooks'.
Is there still an error?
I guess there is a bug somewhere in the "OEmbed" plugin or something else.
Just tested oEmbed and Elgg hooks plugins both.
I don't have any errors; everything works as expected.
I'm using the latest oEmbed plugin from GitHub.
oEmbed plugin is placed after Elgg hooks on the 'Plugins' page.
Good news everyone! (At least for me.)
I figured out the problem. In the e-mail that was sent to me last night was a "bit.ly" link and the oembed plugin tried to embed it, but failed:
#0 /www/htdocs/w00e7451/dubbook/mod/oembed/classes/ColdTrick/OEmbed/Process.php(182): ColdTrick\OEmbed\Process->getOEmbed('http://bit.ly/l...')
I updated the settings of the "oembed" plugin. Before, I had added non-wanted domains to the blacklist, but now I added wanted domains to the whitelist instead. This should prevent it from happening again.
Thanks for the link to "oembed 5.0.3". I updated my version (from 5.0.2). I also moved oembed after Elgg hooks now, just in case.
And also thanks for the instructions to get the error log. Now I know how that works as well.
