To be honest even in Google were only 3-4 cases when somebody in the past had this issue, so it's very very rare.

Hopefully, J3-J4 upgrade method helped.

In that case please:

  1. Delete this file (if you have it): /libraries/autoload_psr4.php or similar with "autoload...." name.
  2. If (1) will not help - delete whole folder /libraries/
  3. and upload that folder from fresh Joomla 4.1 package.
  4. Then if you will be able to login to admin area update Joomla 4

Tip based on: https://issues.joomla.org/tracker/joomla-cms/20828


If 1..3 will not help, you have to install J3 Quickstart and upgrade to J4 from it. I don't have alternative package to share :(

Ciao,

probably durning FTP upload process not all file(s) were uploaded, something is missing/or too much.

  1. Please download Joomla 4.1.5 update package from joomla.org

  2. Unzip

  3. Upload/replace all files from folder: /administrator it may help.

if will not help upload/replace all files also from those folders: plugins, includes, layouts and media.
