Like another user, I am having difficulty installing plugins due to the theme not accepting my account details. I am using my Envato Themeforest username and email and the item purchase code on my license but it will not accept it.
I know the email and username are correct, as I’ve double-checked on the Themeforest site and I know the purchase code is correct because I copied and pasted it from the license. Also I had to put my purchase code in to register here & this website accepted it.
I’m sorry about that, and i’ve been fix those problem now. Please try to remove the plugin file on your site and then go to Appearance → Install Plugins to install the newer version. Or you can upload manually the plugin file into your site that you can find on themes file (jkreativ-themes/plugin). Anyway, may i know which plugin that you want to update?
