When i download all files from themeforest i don’t have child theme inside. This is the reason i am writing here. This is what i have inside theme folder: https://gyazo.com/149fdbeb451f858ed183a6a4611a8927

I have another question. I have installed plugin for caching, but when i activate css caching the custom css in theme options is not working. Can you say me where is the file of custom css from the theme, so i will exclude it from caching?
