When editing a custom post type page with ACF Gutenberg blocks, the acf/ajax/fetch-block call hangs and times out several times. After 30s the blocks load but everything is slow or unresponsive before.
any idea why?
Wordpress 5.2.3
ACF (latest)
Have you found any solution to this yet?
Kind of. We reset all network and browser settings and checked the installed Firewall. It helped a bit, so I guess it was a problem with the queueing of requests, blocked by network issues.
I am only facing this issue at live server and not in wamp localhost. Actually the ACF blocks are using admin-ajax.js to load preview html as well as edit. This is causing more trouble. For every block preview (for fresh load or in editing), there is a request. I don’t know if this will be solved by ACF or not…
However, the native WP blocks are not using admin-ajax.js rather using react.js
Yes, and if one call hangs, all the rest is blocked and timing out, too.
We experienced that as well. Definately need some optimization.
I still have this problem with custom Gutenberg blocks!
This is because dynamic blocks require ajax calls to integrate in Gutenberg editor. This topic is discussed in detail here –
Multiple ACF blocks Failed to load resource: the server responded with a status of 503
