Where and how do i add the code to my (yootheme) template?
It is something about template, normally all template allow you to add custom CSS code in style parameters or in a custom CSS file. Unfortunately I does not have experience with yootheme templates
anyway you can find more informations at
https://yootheme.com/support/yootheme-pro/joomla/custom-assets
And, please an answer on the question: How can i change the (dutch) text above in this popup?
You can find language translations in following files:
- /plugins/jsn/socialnetwork/app/Locale/nl_NL/LC_MESSAGES/cake.po
- /plugins/jsn/socialnetwork/app/Locale/nl_NL/LC_MESSAGES/default.po
Maybe the text is too long and that could be the reason for not showing the cancel button?
I think not, the button should be still visible also with long text
