Hey,
thanks for the fast response.
Well the permissions of the wp-admin folder (and all underlying subs) are 755.
And all files in wp-admin and the subfolders are 644 I think.
I did not make any changes to the permissions.
And if the permissions are not sufficient to delete the wp-admin folder′s content….why is that folder empty after the failed restore…hmmm
Well the main information I gor from you: the effect cannot be caused by the plugin.
So I have to search further.
Thanks
S.
