Thanks a lot, looking forward to test it!

Concering the permission:

ps -aef | grep apache
root 11472 1 0 15:28 ? 00:00:00 /usr/sbin/apache2 -k start
root 19676 11472 0 16:29 ? 00:00:00 /usr/sbin/apache2 -k start

Why are write permissions needed on the lang/ folder?

root@markus /var/lib/wordpress/wp-content/plugins/content-table # l lang/

Concerning the “error.log” entries:
– I install the plugin via WP, then activate,
– when going in “SL Plugins”, “Table of contents” the warning “pumping” starts:

–> in less than 1 minute I get almost 3 million errors:
grep ‘PHP Warning: readdir() expects parameter 1’ error.log | wc -l

… my server seems to be fairly fast 🙂 So, a loop somewhere?

The IP address is dynamic and the one from where I access right now.
