PHP 8.3 Error

[fantomassster]

If you click on the author in the article, the site will see Error: Call to undefined method Joomla\CMS\Application\SiteApplication::getConfig(): implode(): Argument #2 ($array) must be of type ?array, string given

Are you sure this doesn't come from some override or something else?

[fantomassster]

Maybe, but I don’t know how to find out the reason

[fantomassster]

I can’t understand why the author’s profile use T4 framework
/plugins/system/t4/src/t4/MVC/Model/Author.php
Why should I look at the author’s profile URL like this?
/all/author/42-shepetivkacomua.html

[fantomassster]

example https://shepetivka.com.ua/novyny/kultura/17334-vechir-pamiati-heroiv-viacheslava-kucheruka-ta-kostiantyna-mykhalchuka-zibrav-rodyny-pobratymiv-ta-druziv.html

[fevangelou]

It's clear that this plugin overrides the author view in K2. I would recommend you provide as much info as possible about the error into some AI (e.g. ChatGPT, Claude or Google Gemini etc.) to guide you in steps on how to patch T4 (as it's out of the scope of K2's development).

I already did it. As a result, instead of articles, K2 publishes regular articles. And the problem is that there is no such problem on another site, although there is also T4
