Errors after upgrading to Joomla 4

Hi there, I'm using CB 2.9.3+build.2024.10.02.18.57.11.f6795ce5a and I'm upgrading my website from J3.3.12 to joomla 4
The joomla upgrade went fine and everything seems to work except CB, when I try to access the component from the joomla admin I get this:


Fatal error: Declaration of cbjdownloadsTab::getTabTitle($tab, $user, $ui, $postdata) must be compatible with cbTabHandler::getTabTitle($tab, $user, $ui, $postdata, $reason = null) in /home/formalms/testsite.formalms.org/components/com_comprofiler/plugin/user/plug_cbjdownloads/cbjdownloads.php on line 215

Compile Error: Declaration of cbjdownloadsTab::getTabTitle($tab, $user, $ui, $postdata) must be compatible with cbTabHandler::getTabTitle($tab, $user, $ui, $postdata, $reason = null)

Stak trace:Symfony\Component\ErrorHandler\Error\FatalError:
Compile Error: Declaration of cbjdownloadsTab::getTabTitle($tab, $user, $ui, $postdata) must be compatible with cbTabHandler::getTabTitle($tab, $user, $ui, $postdata, $reason = null)

at /home/formalms/testsite.formalms.org/components/com_comprofiler/plugin/user/plug_cbjdownloads/cbjdownloads.php:215


Before the upgrade the CB Jdownloads plugin was installed but unpublished
Any suggestion?

Here a full screenshot of the error page 




 

Please be sure to read errors carefully as generally they indicated exactly where they're coming from. Your error specifically is coming from plug_cbjdownloads. You've a 3rd party CB plugin called CB jDownloads causing your issue. Appears they never updated it to be compatible with CB 2.x. You'll need to contact the developer of that plugin to have them fix that or disable/uninstall that plugin in CB > Plugin Management.

Thanks, since it was in the cb plugin management I didn't tought it may be third party, I will remove it since it's unesed.
Thankyou for you supprt!
