@ Vry6. Thanks for posting. I examined your site and noticed that the issue is that the css file is not being loaded. It seems as though you have another plugin that is obfuscating all you css files, and changing them as new names, but the issue is that if you check the error console for your browser, you will see that it is not finding the css file that comes with Easy Folder Listing Pro.
Specifically, the reason why the file sizes and dates are on different lines is because they are contained in divs that are set to display as block, instead of inline.
