Everything seems to work. But I get this error showing up after installing the Patched Version of alfredb’s Customizer
Warning: filemtime(): stat failed for /home/customer/www/DOMAIN.COM/public_html/tasks/assets/css/app.min.css in /home/customer/www/DOMAIN.COM//public_html/tasks/app/Helper/AssetHelper.php on line 41
Please keep in mind that I’m not a developer of nor a contributor to Customizer. Personally. I don’t use Customizer, and I cannot check all of your plugins.
I’ve verified a clean install of version 1.2.49 with only Customizer, and I’ve got no problem.
Maybe you could remove all plugins except Customizer and then re-add them one by one to spot the issue.
Did you try to copy the file auto.min.css as suggested above?
Would you be friendly to indicate what solved your problem? Is it adding the auto.min.css file or is it deactivation of a particular plugin? Which one? You will thus help others who would encounter the same difficulty as you, thank you in advance for your answer.
When Kanboard introduced selectable themes (light/dark), the file app.min.css was replaced by the fileset auto.min.css, light.min.css and dark.min.css. Any poorly maintained plugin now throws an error, as the requested file app.min.css (usually) no longer exists. Creating the missing app.min.css from auto.min.css makes the error disappear.
Of course, the correct solution would be fixing it in the affected plugin, here Customizer.
