I’m helping a friend to migrate their blog from a “homemade” platform to WordPress and the original developers have not been helpful in extracting the data.

I’d like to use PHP to scrape the site and migrate the content, but first ran into an issue with the fact that the site is loading content asynchronously.

I’ve tried using Puppeteer but have spent hours trying to get past the Chromium issues to no avail. Is there any more stable/straightforward method that someone can suggest?
