Solved How to modify background color in user popup
First of all, thank you very much for your help.
Only a question... ¿where must I insert this code?
Thanks in advance.
You can add a custom.css file via ftp on this location: /components/com_kunena/template/crypsis/assets/css/custom.css.
Then just paste the code there and it should work.
Thank you for the reply!
Done! Works fine!
Thanks again both!!!
I will test it too, and comment here.
