Hi,

Please check setting for option Less(Admin >> SNSTheme >> SNS Twen >> Advance setting >> Less). If you set is Alway compile your .css file will reset with each load site. Please see info bellow

– If you can work with lesscss, please go to Admin >> SNSTheme >> SNS Twen >> Advance setting >> Less: Alway compile and please edit .less files

– If you cannot word with lesscss, please go to Admin >> SNSTheme >> SNS Twen >> Advance setting >> Less: Only compile when don’t have the css file and please edit .css(theme-….css) file

P/S: You can also add your custom css to field Custom Css in Admin panel(Admin >> SNSTheme >> SNS Twen >> Advance setting >> Custom Css)
