Troubleshooting multisite media urls

  • I am setting up a development site which is a copy of an existing wordpress Multisite installation.

    On both sites, media files are physically stored in the usual location (under /wp-content/uploads). But all the links to media files use custom urls, where the string /wp-content/uploads is replaced with files. (E.g. if an image is at /wp-content/uploads/foo/bar.jpg the links point to a virtual url, /files/foo/bar.jpg. This works fine on live, but on dev these custom urls give a 404. The standard urls (with/wp-content/uploads) work fine though

    The live site is one I inherited so I don’t know how this was set up. There are no plugins on there which look like they would change the URLs and I have grepped through the custom plugins and theme and haven’t seen any clues.

    Do you have any idea what might have created these virtual urls and what I could do to make them work on the dev site?

    I have now discovered that replacing wp-content/uploads with files is something Multisite does. Still no idea why it isn’t working on the dev site though

    Sorted.

    It turns out that creating these files urls is something Multisite used to do a few versions ago. Although the live site is up to date, it was created using a previous version. The dev site being created with the latest version was not expecting these urls.

    The answer (for subfolder style multisite; subdomain may be different):

    a) Go into the site settings for each site (/wp-admin/network/site-settings.php?id=<siteid>) and change the Upload Url Path to https/<domain>/wp-content/uploads (same for every site).

    b) Run a query against the _posts table for each site (including the main site) replacing https/<domain>/files with https/<domain>/wp-content/uploads in all the links

    There may be other places this needs to be changed in the DB too.

    By setting the network it is possible to choose the upload folder, whether to use the year-month folders and where to display the images.
    before any action a back-up of the files via ftp and the database is required.
    If you have checked that the back-ups are working, you can use one of the plugins to modify the old URLs in the new ones, never any changes by hand as the plugins may have serialized the paths into wordpress objects.
