I am trying to make a Child theme for my website http://www.retreatdiscounter.com. I am not very good in coding. I have tried following the steps mentioned here: http://codex.wordpress.org/Child_Themes but it doesn't seem to be working. When I activate my Child Theme I get the following error: "Cannot write cache folder. You may try setting the folder cache folder permission to 755 or 777 to solved this."
Can anyone assist me on how to solve this problem?
Thanks in advance for your help.
