這個外掛與 WordPress Importer 有相依性,必須先安裝 WordPress Importer 才能使用。

Substack Importer 安裝方式:

  1. substack-importer 資料夾上傳至 /wp-content/plugins/ 目錄。
  2. 在 WordPress 管理後台的 [外掛] 選單中啟用外掛。


大約 30 秒後,匯入程式停止匯入,並出現空白畫面,該如何處理?

It worked. BUT… it should have an option to (a) make imported posts DRAFTS (even if they were not Drafts in Substack); .(b) use the first image as the Featured Image for imported posts; and (c) option to use import date as publish date so that they’re easier to find (or, alternatively, to set a Category or Tag for all imported posts). Yes, it times out. Not a fatal flaw, but maybe the ability to set a time-out value (or post import speed) would be useful? I used it on the smaller of my two newsletters. I don’t know that I’ll use it on the larger one unless the suggestions of (a), (b), and (c) above are implemented soon.

This plugin does not work with WordPress 6.3:1. The page content is not imported, only a portion of the page header is. 2. The importer reports an error on the first image and makes no effort with other images. The developer has not responded to other support requests in two years.

This is a decent plugin in that it essentially does what it claims to. Although the documentation was sketchy (almost nonexistent), it was easy enough to do the import. I downloaded a .zip file of my substack posts, then uploaded the same .zip file to my WP site from Tools > Import > Substack. The import was pretty quick — maybe 5 minutes at the most. I only started my substack 6 months ago so there wasn’t a lot of data. Then bam! I had a whole bunch of new, published WP blog posts, with the original substack date. (For the most part, that is — there were some date/time issues when the original post was near midnight. I’m assuming that’s due to different server times.) They came in with my site’s styling, which was impressive. Footnotes were more or less there, but not exactly as footnotes; had I wanted to keep them, I would have had to do some cleanup. My substack and blog are heavily dependent on images (I’m a photographer) and, although I could see the correct images in the imported posts, I couldn’t find them in the Media Library. I use each post’s Featured Image in several different ways and couldn’t figure out how to even find the images that I could see in my posts. So I tracked them down. Turns out they are copies of my images and they live on an AWS server. I never gave the plugin permission to make copies of my images or to host them elsewhere. So that’s fatal flaw #1: I’ve completely lost control of my own images. They are on a server for which I have only Read permissions. I’ve already alluded to fatal flaw #2: The images aren’t on my own server and therefore can’t be used as Featured Images in my posts. Fatal flaw #3 would be that when AWS goes down (as it did a few days ago), all of those images would be broken on my site. I unpublished all the newly created posts and began replacing the images. So — aside from the fatal flaws mentioned above, it likely would have taken just as much time to create the posts manually.
