error 500

When you call the UddeIM component in the front end is always a 500 error since yesterday. I have now been updated to version 3.8, but no change. The only change that existed otherwise in recent times, was the Kunena and GroupJive update.
Joomla 3.4.8
UddeIM 3.8
CB 2.0.12
GJ 3.0.1
Kunena 4.0.8

Beim Aufruf der UddeIm Komponente im Frontend kommt seit gestern immer ein 500er Fehler. Ich habe nun schon auf Version 3.8 aktualisiert, aber keine Änderung. Die einzige Änderung die es sonst in der letzten Zeit gab, war das Kunena und GroupJive Update.

Please check if the ItemId (Menu link to uddeIM component) is still correct. When you update uddeIM it might be possible that Joomla uses a new Item Id.

Do you use a 3rd party SEF component?

No matter where I call. On the uddeiM module, the loginmodule of CB or Kunena. Always the same error. And as I said, I've done the update just because the error was.
SEF I only use the Joomla own ways.

In most cases a bug in the .htaccess file causes an error 500.
Was this file updated? Or has the provider updated your server?

The .htaccess has not changed.
Updates to the server it was the last in the last year.
When I turn on SEF comes the same error.

any idea?
