404 error from joomla template after upgrade php version (8)

[dnapas]

I downloaded a free template from the internet, specifically this one:
https://diablodesign.eu/free-joomla-tem ... ersity-104

As you will notice it says that it is compatible with php 8.1.x.
When I started working on the site I upgraded from php 7.4 to php 8.x
however, I keep getting page 404 error, a custom page error from the template.

I contacted the provider who told me that the site can only work with php 7.4
I contacted the template maker and he said he knows the template doesn't work with php 8 but
he does not intend to upgrade it since it is joomla 3. However, in the relevant spot he writes different things and
he is not reliable.

Any advice welcome. If my provider upgrades to PHP 8 the site will be lost...

Welcome to the Joomla forum!

I upgraded from php 7.4 to php 8.x
however, I keep getting page 404 error, a custom page error from the template.

Confirmed. The template produces a 404 error at the front end when tested in Joomla 3.10.12 using PHP 8.0.13. An error log with the option Debug System does not give much information about the root cause:

Code: Select all

IMHO, its better to find a different template for the migration, something that works both in Joomla 3 and Joomla 4 using PHP 8. Alternatively, use your new template in Joomla 3 with PHP 7.4 while you find out about different ways to make Cassiopeia do what you want in Joomla 4, testing the functionality for example in Wampserver, hosted in your workstation:

really shady for the developer to advertise PHP 8.1 compatibility when it's clearly not supported. Start looking for a new template. In the meantime, you can fix the error by changing this line in functions.php:

Code: Select all

return call_user_func_array($name, $args);

to this:

Code: Select all

return call_user_func_array($name, array_keys($args));

The change fix the error, thank you very much I appreciate all your answers.
Unfortunately all the modules deactivated. The rest are allright.
It was a big mistake to not migrate to joomla 4 before trust anyone in the internet. I am looking forward to do so.
