Hi. I'm not exactly new at WordPress but I have jumped ship for a couple years. Recently I've been asked to do some work to make sense of a national church site that has particular accessibility needs. I heard that Rian Rietveld's Twenty Eleven Accessible theme would be worth checking out. Only thing is, I get an error code that keeps me from seeing the installed theme. Site is mostly invisible below the header and menu. It goes like this:
Fatal error: Call to undefined function twentyeleven_content_nav() in /home/uccdm/public_html/wp-content/themes/accessible-twenty-eleven-theme-master/index.php on line 24
Now, I've looked at these forums for that error code but I've found it all very fragmented and I don't really know what I need to do to satisfy this. I have the PHP doc open here so if there is a line that needs fixing, I just need whatever magic anyone has that would help make the theme work, even to evaluate it.
Using different themes I have found that there must be some template hierarchy issues going on, as there have been issues with everything being 404'd if a category search is done. That too I could use some guidance on. I read the lit. I just don't know what is really being asked for.
Oh, and another bit. This site has been someone else's creation and has degraded over time, so I don't know what kinds of funk has accumulated. I did back up the data from the MySQL dbase and have updated to 3.5.1. But I recall from my earlier work that some things are not exactly changed during such version updates and may remain. Is that right? If so, there might be wonkiness I'd not be able to know about until I compare it with a totally new installation. That's something I might do, but not yet since my involvement hasn't been really approved officially.
Help with the theme and error notice would be handy for now. Thanks.
