All of a sudden, when I try to clip almost any website into DEVONthink 3 as a Formatted Note (Clutter Free), I get this message:

> Request Entity Too Large
> 
> The requested resource does not allow request data with POST requests, or the amount of data provided in the request exceeds the capacity limit.

Occasionally it gives me this message:

> Please enable JS and disable any ad blocker

Even when I disable adblocker, it does not work. It does this when I use the Clip to DT browser extension in both Chrome and Firefox. I’ve tested multiple domains (NYTimes, New Yorker, Financial Times, the Economist, WSJ, etc.) and it’s still true. I’ve restarted my machine and it still happens.

However, DevonThink3 is still able to clip all of these sites as rich text, plain text, HTML, bookmark, web archive. It’s just Formatted Note and Markdown that have this issue. (I don’t personally use Markdown, just Formatted Note.)

I only use Devonthink3 locally (no DEVONthink To Go or syncing is occurring), and I don’t think any of my network settings have changed… anybody have any idea what could be causing this?

Related: Does DevonThink4 still have Formatted Note / Clutter Free clipping available? Anybody have any complaints about that?

DEVONthink 3 is retired from development.

> All of a sudden

It may be _“sudden”_ but what precipitated the change. Updates to your system, new hardware or firmware, e.g., on your router, the increasing use of Cloudflare by more and more sites, etc? The last version of DEVONthink 3 was released in June so it’s nothing we’ve changed.

And yes, version 4 is superior in many ways, including new and improved clipping with better clutter-free captures, a new Reader view in DEVONthink, etc.
