Sensei: Fatal error with WordPress 4.7

[danjjohnson]

Steps to reproduce:

• Update to WordPress 4.7
• Create a new lesson, and assign it to a course containing modules.
• Now assign the lesson to a module and update

You will see a blank screen with:
Catchable fatal error: Object of class WP_Term could not be converted to string in /srv/www/sensei-master/htdocs/wp-includes/taxonomy.php on line 2285

For what it's worth, this happens on WP 4.6.X as well. I'm unable to add lessons to modules on WP 4.6.X

[lisaleague]

@scottwyden no issues with lessons/modules in 4.6.1, have you tried that?

[scottwyden]

It doesn't work with 4.6.1 either

[lvnilesh]

I repro this exact issue in wp 4.7 but master works at 4.6.1

[scottwyden]

I'm not even on 4.7 yet and still have the issue (on 4.6.1)

[lvnilesh]

try master?

[scottwyden]

If you're referring to the master from github, no I haven't tried it. I've unfortunately had bad experiences when trying updates from WooCommerce, so I worry it will break things further.

[lvnilesh]

Why worry? Try all things in a staging area first.

[scottwyden]

Because staging isn't always a true sign of what will happen. There are other things in play. Many times I've updated Woo/Sensei on staging, and locally, with no problem. But once it hit a live server with caching in play, etc, things broke. So I'll wait for an official update before seeing if the issue is fixed.

[scottwyden]

For the hell of it I just tried the master and it still doesn't work for me on 4.6.1.

[lvnilesh]

You may have other trouble makers installed not just this. Try disabling one plugin at a time and keep narrowing down to isolate.

[pgk]

Can reproduce only for 4.7. Works fine in 4.6.1

👍 Thanks @pgk

@pgk possibly related error with courses:

• Edit a course
• Select (or add) some modules for the course
• Update the course

I get a blank screen with:

Seeing the same thing. Posted a question about it on wordpress.stackexhange.com over here with some code snippets and debugging results.

[pgk]

@mlwilkerson which version of Sensei are you on? This issue was addressed in 1.9.11

[pgk]

@mlwilkerson if you are referring to #1698 specifically, it will be addressed in the next release

[mlwilkerson]

@pgk Thank you. Yes, I did update to 1.9.11 (I should have done that in the first place, of course). It did resolve my immediate problem, which was: the error thrown when updating a lesson that was assigned to a module. #1698 looks related (WP_Term object returned when an array of ids might have been expected), but didn't happen to be the exact same usage scenario in my case.
