Broken Enjin Theme?

My forum is being rejected by the RPGfix directory. I am told that while my affiliate link to RPGfix is working, there are errors in the site theme's code which are causing the bot to reject it.
Does anyone have experience with Enjin themes? I picked enjin because I am very new to coding/html etc and their site manager streamlines the process a lot. My theme is also an enjin theme, so I know almost nothing about how it works or what might be broken. How can I work out where the issue is?
