Hi! I was upgrading from 1..1.2 to 1.1.3 but after I had filled in all my server details this error message appeared: "You have already completed installation. If you wish to reinstall, please delete the file internal_data/install-lock.php." When I was uploading the new files I took replace old files and not merge. Could this be the problem? What happens if I delete install_lock.php? Pleasehelp me with this.
