It does not work for my upgrade on https://www.pfadiblog.de.
I god a header-send-error after copying the new files and had to rename the simple-tags-pluginfolder in order to get wp running again.
An now, when I reactivate, I get it again:
Warning: Cannot modify header information – headers already sent by (output started at /srv/www/asdf/www.pfadiblog.de/asdf/wp-content/plugins/simple-tags/2.5/simple-tags.client.php:4300) in /srv/www/asdf/www.pfadiblog.de/asdf/wp-includes/functions.php on line 698

Btw. on the other hand: It did work with my other server https://www.fly.ingsparks.de.
Must be some problem with different php/server-configuration?
