it struck me today, that the information text in the "Custom CSS" tab still claims, that the file custom.css must be stored in the «templates» folder. This is outdated; the file custom.css must be in the media/templates/site/j51_layla/css folder. Otherwise it will not be loaded.
Load custom.css. Place the custom.css in your templates CSS folder (../templates/[YourTemplate]/css/custom.css
For me it is ok, I have been familiar with this new Joomla policy for a while now. I just wanted to make you aware of this wrong information, since it could be suitable to mislead some of your customers.
Thank you and kind regards
