[RESOLVED] Apparent login module crash when upgrading Joomla 4 website to php 8.0

[roscofil]

Steps to reproduce the issue

Have a website using a std Login module which is working just fine with Joomla 4.2.2 and php 7.4.x
Activated php 8.0: website crashes with "count(): Argument #1 ($value) must be of type Countable|array, null given" error message on frontend.
Go to admin panel, turn off the login panel module: the site gets back to life without problems.

Expected result

Login panel should be working ok.

Actual result

Crash as seen on the attached image (crash.jpg)

System information (as much as possible)

Joomla 4.2.2
php running on Linux info 3.0 #1337 SMP Tue Jan 01 00:00:00 CEST 2000 all GNU/Linux
MySQL 5.7.38-log
PHP version: 8.0.22
Template by Smartaddons (SJ TopDeal)
Joomshopping 5.0.7 (declared by Joomshopping as compatible with php 8

Additional comments

No additional error message when turning debug to maximum

Thanks and best regards

1. Please enable debug in the global configuration and repeat. That should give more verbose error messages
2. Please switch to cassiopeia and repeat step 1

Hello,

Thx for your reply:

1. Switched debug to on and error reporting to maximum, login module enabled.
   Got the following error:

Uncaught Throwable of type TypeError thrown with message "count(): Argument #1 ($value) must be of type Countable|array, null given". Stack trace: #0 [ROOT]/modules/mod_login/mod_login.php(34): require() #1 [ROOT]/libraries/src/Dispatcher/ModuleDispatcher.php(52): include('/homepages/5/d6...') #2 [ROOT]/libraries/src/Dispatcher/ModuleDispatcher.php(55): Joomla\CMS\Dispatcher\ModuleDispatcher::Joomla\CMS\Dispatcher{closure}('/homepages/5/d6...', NULL) #3 [ROOT]/libraries/src/Helper/ModuleHelper.php(276): Joomla\CMS\Dispatcher\ModuleDispatcher->dispatch() #4 [ROOT]/libraries/src/Helper/ModuleHelper.php(161): Joomla\CMS\Helper\ModuleHelper::renderRawModule(Object(stdClass), Object(Joomla\Registry\Registry), Array) #5 [ROOT]/libraries/src/Document/Renderer/Html/ModuleRenderer.php(99): Joomla\CMS\Helper\ModuleHelper::renderModule(Object(stdClass), Array) #6 [ROOT]/libraries/src/Document/Renderer/Html/ModulesRenderer.php(50): Joomla\CMS\Document\Renderer\Html\ModuleRenderer->render(Object(stdClass), Array, NULL) #7 [ROOT]/libraries/src/Document/HtmlDocument.php(565): Joomla\CMS\Document\Renderer\Html\ModulesRenderer->render('cart', Array, NULL) #8 [ROOT]/libraries/src/Document/HtmlDocument.php(847): Joomla\CMS\Document\HtmlDocument->getBuffer('modules', 'cart', Array) #9 [ROOT]/libraries/src/Document/HtmlDocument.php(633): Joomla\CMS\Document\HtmlDocument->_renderTemplate() #10 [ROOT]/libraries/src/Application/CMSApplication.php(1017): Joomla\CMS\Document\HtmlDocument->render(false, Array) #11 [ROOT]/libraries/src/Application/SiteApplication.php(714): Joomla\CMS\Application\CMSApplication->render() #12 [ROOT]/libraries/src/Application/CMSApplication.php(299): Joomla\CMS\Application\SiteApplication->render() #13 [ROOT]/includes/app.php(61): Joomla\CMS\Application\CMSApplication->execute() #14 [ROOT]/index.php(32): require_once('/homepages/5/d6...') #15 {main}

2. Switched template to Cassiopeia and restarted: got the same message when the login module is enabled.

Thx

Philippe

It seems to clearly be coming from the login component/module: I unpublished the faulty module, tried to recreate one from scratch, using any position of the template and it always fail...

[brianteeman]

please post the stack trace from when you are using cassiopeia

(also accodring to the smartaddons site you are not alone in having issues with their templates and 4.2 - have you contacted them for support?)

[roscofil]

Yes, I did contact them but they indicated that this was probably due to the Joomla Login module and that I should contact the Joomla team :-)

Stack trace with Cassiopeia below...Looks the same to me...

include('/homepages/5/d6...')

This tells me that something connected with the template is still running

[roscofil]

HmmmmProblem is I am not sure I can see what the thing is...I'll try again...

Is there any way to expand the path in this stack trace or to find it elsewhere? Dump?

[Abernyte-Git]

Does the template have a mod_login override?

---

_{This comment was created with the J!Tracker Application at issues.joomla.org/tracker/joomla-cms/38749.}

[roscofil]

You may be right. Am not near my system but I’ll check when back. Should I then just simply remove it?
Thx for the heads up.

[roscofil]

@Abernyte-Git:

You were right! Thisis what causes the issue!
Didn't think about checking this...Thanks so much for pointing it. Will now have to have smartaddons figure how to fix it...

Cheers

Philippe

[brianteeman]

That's what I thought it would be but you said it had the same error when using cassiopeia and that should not have been using the template override. weird

[roscofil]

Agreed...
Thanks for helping, man!
