errors after upgrade to joomla 4.2.4

[HarryT2]

I tried to upgraded my Joomla 3.10 site to 4.2.4 and updated phocadownload to 4.0.4
My site uses php 8.1
The upgrade itself went without problems and no error.

When I click on a link to phocadownload I get an error and have no idea how to solve this.

The traceback of the error is:

Any idea how to solve this?

Hi

If I use an empty new site and load it with Phocadownload, the instructions work. However I have an existing site and want to upgrade the site. Then I get the error form above.

If if I uninstall phocadownload and almost every extension before upgrading and reinstall phocadownload on Joomla 4, emtpy the tables and insert the dump form joomla 3 I get the same error.

Are there instructions how to upgrade an existing installation?

Hi, there are many different ways. You can export data and the files, then uinstall the old component and install new one and import data and the files (of course with all backuped data, etc.). The the same guide should be used (the only difference is, that you uinstall the old version)

The issue is solved with the phocadownload 4.0.5beta5 version.

I have no idea how to mark this post as solved.
