Installation & Errors
In short: unzip, keep the files in a folder called
Jeffrey Friedl (author of many LR plugins) wrote an amazing article about how to install those plugins. It is the best article so I don’t even want to attempt to write a better one. It is here: Installation and Management of LR Plugins.
In the Media Library, the images are ordered by a field internally known as Upload Date, it is shown as the Date column. So basically the latest image you upload will be at the top. In Lightroom, you can choose that by drag & drop the images about to be sent for the first time (in New Photos to Publish). Then Publish. The last image to be uploaded will appear first in the Media Library.
Another way is to use the Use Photo Taken Date. I recommend this because the plugin will override the default process and use the Taken Date of the photo as the Upload Date. That will make your Media Library clean, with useful and re-usable data.
If you want to order images within a gallery synchronized by WP/LR Sync, this is possible. You need to use Custom Order in Lightroom for this specific gallery, and trigger a Re-Publish for any photo within this gallery to trigger this ordering update.
Of course, this could be the cache at many different level, so depending on the plugins and systems you are using for this, the way to resolve it is very different. Photon is also known to do that.
The only way to make sure the new image has been uploaded and synchronized, is to download the file by FTP and open it. Please do this before trying to check if there is an issue with the plugin itself.
Another way is to take advantage of the API available in WP/LR Sync. One of my users, Geet, wrote some code that keeps his custom meta (city, country) synchronized from the IPTC information. The code is available here.
Post Types Extension
Is the Hierarchy is right but your WordPress doesn’t have the Posts/Pages/Galleries (or whatever you linked it to) the same, try to Reset the Extensions, then Sync the Extensions again (in the Extensions menu). That will call your extensions (and therefore, the Post Types extension) to re-do everything.
Issues with Extensions
Real Media Library
If you are a user of the Real Media Library extension built-in WP/LR Sync, this extension is now deprecated and has been removed from the plugin in 2019. But don’t worry, that doesn’t mean that you are not able to use WP/LR Sync with RML, on the contrary! Matthias – the developer of Real Media Library – is in charge of the extension of his plugin.
Install the extension made by Matthias. It is available on the WordPress repository, here: WP/LR Sync Folders.
If any issue with this extension, please use the Support Threads related to the plugin. They are here. Also, don’t hesitate to leave a review for Matthias’ hard work. Thank you :)
