After an upgrade, can I delete the contents of the "upgrade" folder?
PermalinkI tend to rename the root 'concrete' folder to 'concrete1', then move 'concrete' folder from the 'updates folder' into the root.
Then remove the last bit of code.
<?php define('DIRNAME_APP_UPDATED', 'concrete5.6.0.2');?>
Normally works!
If you have limited space, then I suggest you do manual upgrades instead and replace the core manually.
