I am using the "Namo" theme and I cannot access the "Namo Options" under the appearance section. I also have this same issue with http://www.agondacottages.com. I am not that knowledgeable with code/php but I followed your previous advice and created a debug.log file. please use the following google drive link to download: https://docs.google.com/document/d/1qweksYuunCmx1vq2vPqWCRAeszuLWMFGmwfTZdvrpuw/edit?usp=sharing
I would really appreciate if you could get this working for me. It would also be great if you could advise me of the issue as I use the same theme on other sites and it would be great if I could fix it myself. Thank you
