Joomla 3.6.4, php 5.6.23.

Other reasons?

Php is now updated to version 7.0.8 and everything seems work fine.

Hello reply,

Please can you provide your JEvents Support Info from the JEvents Control Panel on your site?

Many thanks
Tony

Hello,

I see no reason for this not to work. Do you still see:

Fatal error: Cannot redeclare class JFormFieldTextarea in /home/xxxx/http://xxxxx.fi/libraries/joomla/form/fields/textarea.php on line 167

error? Can you go to the Joomla! updater and re-install core files anyway.

Many thanks
Tony

Everything works fine now. Error disappeared when php was updated. Quite mystic anyway.

Ok, thanks for letting us know.
