Version 2.0.2 does not fix the problem !

Hi,
I don't know why code is not updated. I'm not an expert with Nextcloud, but I believe you can clear php cache

Check code for DrawioPreview.php it doesn't have a call to getPreviews now in v2.0.2

[marcatsmci]

OK, never seen that before!

Disable + delete application + reinstall: does not work

Delete the application + stop php-fpm + stop Nginx + restart + reinstall the application: works!

I've been using Nextcloud since Owncloud (at least 10 years!) and this has never happened.

I don't know who is at fault : Nextcloud or draw.io...

You can close the issue, thanks

Thanks for the info. Another user also had a similar issue but was opcache to cache php.
