2.a. To be perfectly clear here, this isn't text. This is a .jpeg I made in Photoshop of text, so that it can be anti-aliased. The graphic seems far too small for its actual pixel size. ShowKase appears to be 'scaling it down' (it is not 1:1 pixels to screen resolution) and I can't get to the bottom of what is causing that.
Showkase scales the Site logo depending on the size of the user's browser window.
To be clear on the issue with those folders, they are empty. There are no visible files in them. At least not according to CoreFTP. But it still wont let me delete the folders.
Make sure that your FTP program is set to show hidden files before checking that the directories are empty.
If this does not help, log into your web hosting account using a browser and try deleting the directories through the File Manager in your web hosting account's cPanel.
