Stuck on wrong confguration file found

I upgraded to 2.4 on J1.5.23 (backed up configuration, uninstalled 2.2, executed the SQL commands and installed the component), and after successful installation I get:

I click on "continue", but just get redirected to this same page and can't get into uddeIM's backend.

Any clues?

Having the same issue. Not much luck on my end.

Damn, forgot to increase the version number of the config file:

The fix is quite simple:

In admin.uddeim.php change line 20 from
$configversion = "1.8";
to
$configversion = "1.9";


Sorry for that. I have updated the package.

Found it in admin.shared.php, thanks.

Here two years later I get the same, but in ver. 3.3 on joomla ver 3.2.2

In danish:

Forkert konfigurationsfil fundet!

Version fundet: 2.4
Version forventet:

Konverterer konfiguration...

Done!

How/where can I fix it

Well, can you try to switch off uddeIM integration in Kunena. In

it is said that this might causes trouble.
