It appears to be happening because of a fatal error in the YARPP plugin, as indicated by the error message below the Related Posts heading.
Fatal error: Call to undefined function yarpp_sql() in /[yourserver]/www.izzile.com/wp-content/themes/aurium/aurium/single.php on line 80
Because of that error, the page stops loading there so the sidebar just never gets loaded.
Immediate solution will be to deactivate the Related Posts plugin and see whether you can then see the sidebar.
Thanks for the help, but I don’t even have that plugin- which is probably the problem! Let me see if that makes it work.
Thanks a bunch! That fixed it!
I have similar problem. I deleted Related posts plug in. Looks like it doesn’t. Resolve my issue. Still have no sidebar at the single post. php code that includes the sidebar is in place. Could any one help me out ?
