Hi,

the included plugins are visible, (the says Warning: This plugin requires a later version of Elgg!) independent from the permission.

As i wrote i've try to set 755, 775 and 777 for mod folder of course with -R for subfolders and files.

I think with 777 it must works, but was't successful.

I run it under ispconfig3, uploaded via ftp, so the ownership and group settings are must be correct.

If the plugins that come with Elgg are showing the error message "Warning: This plugin requires a later version of Elgg!", something is very messed up on your install. Why don't you delete everything and start over.

Good idea :)

I did. I found a useful howto : http://www.howtoforge.com/installing-elgg-on-an-ispconfig-3-system

I think my 1th error was: I didn't change permission of engine folder to 777 before ran the installer, and didn't change back to 755.

the 2nd: I did use -R for chmod on plugins.

as is see: all the folders must be 755 and files 644 after install.

Now looks ok. Thx for your help and time, Cash!
