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/](http://DOMAIN.COM/)/public\_html/tasks/app/Helper/AssetHelper.php** on line **41** ---

Sounds well known. But I’m on the road now, don’t have time. I’ll have a look ASAP. ---

> [@kenh](#): > > app.min.css I don’t know which module requested that nonexisting file _app.min.css_. It’s no longer present in current versions of Kanboard. - Which version of Kanboard are you using? - Which plugins are you using? You can try to **copy** the file _auto.min.css_ as _app.min.css_. This should make the error disappear. ---

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? ---

alfredb: I don’t know why you are so kind and responsive to a newb like myself. I’m just really grateful that you cared to reply to me. And yes, your suggestion worked! Thank you so much. Not just for helping me solve this issue. But, helping me not feel alone with this problem. ---

You’re welcome! In case of other issues, don’t hesitate to ask. ---

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.
