How do I get a support? All the customers who purchased our products from ThemeForest can get a technical support via this forum. If you have some pre sale or general questions, please feel free to contact us via a contact form on TF.
How long should I wait to get a response? We will try to assist you shortly but usually it takes 24-72 hours it depends on the number of requests. But do not forget to read the documentation which comes with each product before submitting your requests. Please note that I do not provide support on weekends, I like to have the rest these days like you do.
