You can report to us if still not working for you.
We are here to help you !!
Have you tried the same uvdesk version on your local machine (localhost)
if not then please check. May be some issue from your server.
We have checked if the same issue exist with us but we are not facing the same anywhere and everything working fine.
Please share the steps you are doing and when this error comes.
Also mention what version of UVdesk opensource you are using.
Have you checked your console to see what exactly the problem is coming when changing the status.
As normally it never happens.
Thanks for your contribution !!!
We have updated your suggested line of code in our project master branches you can check.
Hope you will contribute the same in near future for this opensource project.
Stay tuned with us here we are also adding new features with this project as well.
Please share the original file with the same extension we will test if there is any issue from our side.
Another point: user that update from zip need backup some files, resume that and replace the new public folder with the old one so it will not miss favicon, attachments, logo, etc.. but by doing that if you made for example update to css in the public/bundles user will loose updates.
You can run below command and will get all latest CSS and Js automatically update in public folder anytime.
php bin/console assets:install
