I got this error when I try to preview the newsletter templates. I already set the permissions for the files to full access. May there is an issue with Bulletproof Security? Could you give me hint, where I have to look. Thak you very much! Mike November 14, 2015 at 1:52 pm #18932 StefanoKeymaster Could be that plugin. It many time blocks access to the wp-content/plugins requests. Author Posts Check out our premium plans with priority support.
