Thanks very much for the reply! Works great!

Now the whole backend goes blank after I press login. And this is one out of six error messages displayed:

Warning: Cannot modify header information – headers already sent by (output started at …/wordpress/wp-includes/functions.php:3468) in …/wordpress/wp-login.php on line 353

It works even though that message is displayed. But now I see two more error messages in settings > excerpt when saving:

Notice: Undefined index: advancedexcerpt_no_custom in …/wordpress/wp-content/plugins/advanced-excerpt/advanced-excerpt.php on line 262

Notice: Undefined index: advancedexcerpt_finish_sentence in …/wordpress/wp-content/plugins/advanced-excerpt/advanced-excerpt.php on line 265

The error messages are not displayed if the boxes are checked in settings > excerpt.

I′ll try that. But the last time I had it on(not sure if debug is on) the whole site stopped working and there were a couple of error messages.

I′ll get back to you when I′ve tried it again.

Thanks for the reply!
