I set latest version and it works, but when I change css for my own css, it doesn't work. Somewhere I did mistake. If you can, see please, by myself I can't fix it. Thanks.
Do you mean you've make some customization on css?If yes, I am really sorry but unfortunately we cannot accommodate your request currently as it is beyond our support scope's policy as outlined in http://stackideas.com/support
Having said that, if you require us to perform the customization for you, you can always request for a quote from us at https://crm.stackideas.com and select "Customizations" . Our sales person would be glad to send you a quote for the customizations that you have requested.
