JetPack Incompatibility

[phillcoxonParticipant]

I’m running UpdraftPlus Pro 2.6.14.24 on a site, and I’m getting the following error output into my logs:

Notice: can_display_jetpack_manage_notice used for an anonymous function is deprecated since version with no alternative available. in /app/public/wp-includes/functions.php on line

After searching through the entire codebase for the site, the only reference I found, outside of JetPack, to the can_display_jetpack_manage_notice function was inside of updraftplus/udaddons/updraft-addons.php on line 65. It appears that that line is what’s causing the issue. Can you please look into this? Thank you.

Hi Phill,

updraftplus/udaddons/updraft-addons.php on line 65

That line uses a named function, not an anonymous one, so can’t be what you’re looking for. Anonymous functions start like this: function () {. See: https://www.php.net/manual/en/functions.anonymous.php

JetPack uses the is_callable() (https://www.php.net/manual/en/function.is-callable.php) PHP function to determine whether a function is anonymous or not while outputting notices about deprecated functions (https://plugins.trac.wordpress.org/browser/jetpack/trunk/class.jetpack.php#L6394). The __return_false() function (https://developer.wordpress.org/reference/functions/__return_false/) must be evaluating as is_callable() by PHP.

I can tell you with 99% certainty that line 65 in updraft-addons.php is the line that’s causing the PHP notice.

Same issue here.

Any (simple) solution?

Thanks.

Inclined to agree.. when I disable UpdraftPlus (which is not what I want to do) the error as described goes away.

Hello, I have the same problem. Is there any help for this?

[DavidParticipant]

I did ultimately comment out line 65 in updraft-addons.php and enabled the plugin.

[davidecholsParticipant]

Thank you David! I’ve done that now and the notice is gone, what effect might this have on Updraft? Thank you again.

Thanks Phill for raising this issue.

I see exactly the same error message:

Notice: can_display_jetpack_manage_notice used for an anonymous function is deprecated since version with no alternative available. in /home/mybraini/public_html/wp-includes/functions.php on line 4438

The error message appears on every page of the live version of my website, which is unacceptable.

The error message disappears when I disable UpDraftPlus. I have disabled UpDraftPlus as I am not prepared to comment out PHP in case it has an adverse effect but also because it is the responsibility of UpDraftPlus to investigate this properly and fix it if it indeed a bug.

I pay for the Premium version of this plugin so have now raised a support ticket asking for this issue to be investigated properly and fixed asap.

Will update this thread when I hear back.

Hi,

This is a bug in Jetpack which they have slated to fix in the upcoming JetPack 7.3.1: https://github.com/Automattic/jetpack/issues/12303

Sorry for a lack of reply here. One of our support staff flagged it for a developer to look at, but in an incorrect way that did not work.

Best wishes,
David

Also, you will want to look into why your PHP install is configured to send PHP internal information to the web browser, and turn that off (e.g. WP_DEBUG turned on, or PHP error reporting configured to print instead of log), as that is rarely desirable on a live website.

Hi,

Looking again at https://github.com/Automattic/jetpack/issues/12303, it says that they *did* update it in JetPack 7.3.1, which they released two weeks ago; please check that you have updated. (If not, you should re-open that issue).

Hi David,

Many thanks for your quick and helpful response, much appreciated. I have JetPack 7.3.1 installed, but still see the issue so have re-opened the issue on Github.

Not sure why the error was going to the web browser. Will contact my host to explore further.

Hi,

I’ve reviewed this again more carefully. In fact that issue on the Jetpack tracker is subtly different. In fact, the relevant line of UD just needs removing. I have now done so from our development version, so it’ll be in the next release (due out in a few days). It’s also removed from all new downloads of the current release. You can comment it out without harm. You will still want to not have PHP debugging output go to the browser, as otherwise you may see all kinds of things from many plugins in future.
