Unable to update Joomla 4.0.2 to 4.0.3 Error: "" is not valid header name

Post by kakem » Thu Sep 16, 2021 9:41 pm

Hello,

I am new to admin of Joomla, and could migrate to 4.0.0 and update to 4.0.2. Nevertheless I got now the following error: "" is not valid header name
And with debugging, the following:
Call stack
# Function
1 ()
2 Laminas\Diactoros\HeaderSecurity::assertValidName()
3 Laminas\Diactoros\Response->assertHeader()
4 Laminas\Diactoros\Response->setHeaders()
5 Laminas\Diactoros\Response->__construct()
6 Joomla\CMS\Http\Transport\StreamTransport->getResponse()
7 Joomla\CMS\Http\Transport\StreamTransport->request()
8 Joomla\Http\Http->makeTransportRequest()
9 Joomla\Http\Http->get()
10 Joomla\Component\Joomlaupdate\Administrator\Model\UpdateModel->downloadPackage()
11 Joomla\Component\Joomlaupdate\Administrator\Model\UpdateModel->download()
12 Joomla\Component\Joomlaupdate\Administrator\Controller\UpdateController->download()
13 Joomla\CMS\MVC\Controller\BaseController->execute()
14 Joomla\CMS\Dispatcher\ComponentDispatcher->dispatch()
15 Joomla\CMS\Component\ComponentHelper::renderComponent()
16 Joomla\CMS\Application\AdministratorApplication->dispatch()
17 Joomla\CMS\Application\AdministratorApplication->doExecute()
18 Joomla\CMS\Application\CMSApplication->execute()
19 require_once()

I am not sure what I should do and would greatly appreciate your help.

How did you update - through Joomla Update?

You have sufficient user access (super user) to do the update?

It could be PHP settings - e.g. file upload or post size limits are too small (smaller than the update package of Joomla) and causing it to fail.

Can you restore from a backup and try again?

Did you see any other errors - is the PHP error reporting turned on, this would give more clues (or maybe refer to the error log in Joomla or on your hosting)?

The important information is contained in

Code: Select all

Laminas\Diactoros\HeaderSecurity::assertValidName()
See discussion about updating over stream with cURL deactivated in https://issues.joomla.org/tracker/joomla-cms/31330

Check if you have cURL disabled in your PHP environment and, if so, enable it.
