Edit /var/www/conf/bootstrap_repositories.php and change the value for three instances of “RECYCLE_BIN” to an empty string:
i.e. Change:
#grep -in 'RECYCLE_BIN' /var/www/conf/bootstrap_repositories.php 38: "RECYCLE_BIN" => 'recycle_bin', 76: "RECYCLE_BIN" => 'recycle_bin', 134: "RECYCLE_BIN" => 'recycle_bin',
to:
#grep -in 'RECYCLE_BIN' /var/www/conf/bootstrap_repositories.php 38: "RECYCLE_BIN" => '', 76: "RECYCLE_BIN" => '', 134: "RECYCLE_BIN" => '',
The changes are effectively immediately after logging off.
