Hi… since updating to PHP8.3 I am seeing the warning
Warning: Attempt to read property "id" on null in /home/[...]/wp-content/plugins/buddypress/bp-xprofile/bp-xprofile-template.php on line 558

Any idea what’s up, please?

WP 6.7
BP 14.2.1
PHP 8.3

Hi,

It is difficult tell since the error message is missing backtrace info. Furthermore, I’m not getting that error with:

• WP 6.7
• BP 14.2.1
• PHP 8.3

Just for GP and long story short, I placed the function bp_get_the_profile_field_id(); in functions.php of a child theme in an attempt to replicate the error. Query Monitor revealed the error was caused by the aforementioned function, see the following screenshot:

I am still seeing this error when editing the extended profile.
Now on:
WP 6.9.4
BP 2.6.4
PHP version 8.3.30

The following error now has trace back:

Warning:  Attempt to read property "id" on null in /home/<xxx>/public_html/ovni-owners/wp-content/plugins/buddypress/bp-xprofile/bp-xprofile-template.php on line 558

Whoops – hold off responding to this for now. I may have found the cause.

Closing this topic. I have found it is caused by a filter of my own :-#)
