The enable media replace plugin does not appear to be working correctly in Wordpress. When I choose the option to "just replace the file", i.e., update the file while preserving the original links, it still pulls up the old copy of the pdf file. However if I choose the second option, i.e., upload the file with a new file name and links to the new file, it will display the latest version. How can I get it to show the latest version of the file while still keeping the original URL? I could upload a new file with a new name, but this would mean having to update all the links on the website and document templates which is a lot of work.
