Errors (in console AND server logs) on deleting or selecting images from panel

Kirby 3
1

Hello all,

Not really sure what is wrong, but in a new install of Kirby we have a lot of problems with images. Uploading images work fine. Srcset seems to also work and generates thumbs in the Media folder.

But:
When clicking on delete, or clicking on select the panel freezes. In the console we get the following error (actually hundreds of them):

app.js:1 Uncaught RangeError: Maximum call stack size exceeded.

In the error log of Nginx we get this:

2019/11/11 15:15:29 [error] 27525#27525: *4349 FastCGI sent in stderr: "PHP message: PHP Warning:  Cannot modify header information - headers already sent by (output started at /var/www/stage/index.php:5) in /var/www/stage/kirby/src/Http/Response.php on line 275" while reading upstream, client: 89.20.163.66, server: EDITED, request: "GET /media/pages/work/dutch-police/1444430157-1573467880/EDITED.webp HTTP/1.1", upstream: "fastcgi://unix:/var/run/php/php7.2-fpm.sock:", host: "EDITED", referrer: "EDITED"

Not really know where to start looking. We tried both Imagemagick and GD.

What does work:

  • uploading files
  • generating thumbs (scrset)
  • generating a webp image for newly uploaded files (hook file.create:after)
  • generating a gif for uploaded mp4’s

We are running NGINX on Ubuntu 18.04 and PHP 7.2.

I have other websites with the same server setup, that DON’T seem to have this problem. Just looking for a direction to look into. Any ideas?

Headers already sent seems to point to an issue in one of your files, maybe the config or so. Make sure not to have any whitespace or something like that.
