I have an older blog which I am upgrading from a 2.x series to the current stable 6.11.3 series using the upgrade procedure given online.

Process: I backed up the database, then manually deleted all of the old base /b2evolution/ files except media/ , conf/_basic_config.php, and skins/your_custom_skin_folders.

I downloaded and unzipped the new version, and ftp uploaded them to the b2evolution/ base folder. I then ran the installer.

I got two persistent error messages and took screenshots of the full messages. The abbreviated version errors are:

1.) "Preparing to install /.htaccess in the base folder... (Force=no)
"ERROR!
"Failed to copy sample.htaccess to test folder! "

I then manually copied sample.htaccess from b2evolution/ to test/ , though the error persists.

2.) Received the following messages:

Upgrading data in existing b2evolution database...
