cb.menu.php deprecation error

upgrade to Joomla 4.3.2,  php 8.1.18 and the latest version of CB is giving me this error:

Deprecated: sprintf(): Passing null to parameter #1 ($format) of type string is deprecated in .../components/com_comprofiler/plugin/user/plug_cbmenu/cb.menu.php on line 340

I can't tell how $this->htmlDown is set. I dumped to screen and it appears to be a non-empty array of strings:

array(3) { [0]=> NULL [1]=> string(96) "

• • " [2]=> string(96) "
  • • " }

So I suppose level = 1 would return a null.
 

It's a deprecation notice. Nothing to be alarmed about, but thank you for letting us know and have added a bug ticket to fix in a future release. It is not an error and will not impact the function of anything. Reduce your error reporting so it doesn't output.

Yes, thanks, just a warning. You had said you were trying to fix these. That's just one of a couple hundred I see everytime I view my CB Profile. Maybe 1 of them is coming from a customized CB template I made back in J3 which I will need to fix.

Unique list:

Deprecated: htmlspecialchars(): Passing null to parameter #1 ($string) of type string is deprecated in /usr/local/J4/components/com_comprofiler/plugin/user/plug_cbactivity/templates/default/activity/container.php on line 41

Deprecated: explode(): Passing null to parameter #2 ($string) of type string is deprecated in /usr/local/J4/components/com_comprofiler/plugin/user/plug_cbactivity/library/CBActivity.php on line 2297

Deprecated: htmlspecialchars(): Passing null to parameter #1 ($string) of type string is deprecated in /usr/local/J4/components/com_comprofiler/plugin/user/plug_cbactivity/component.cbactivity.php on line 2542

I'm also seeing this a lot even though I have raised "memory_limit" to 256M in php.ini.

Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 10179584 bytes) in /usr/local/J4/libraries/vendor/joomla/registry/src/Registry.php on line 80

Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 34529280 bytes) in Unknown on line 0

What do you do about that?
 

CB Activity deprecations are fixed in current CB Activity 6.0.0 development branch that isn't released yet.

Regarding memory limit issues that's coming from Joomla's own Registry class. So I'm guessing a 3rd party plugin of some kind is loading too much into it. Try enabling debug mode with maximum error reporting to see if it'll give you the full error trace so you can see what's calling it.
