Encounters Lite

I updated my encounters lite theme and now my pages/menu links won’t work and I also can’t get 5 repetitions of my right side bar from below my top widgets on my home page and it has my blog in sudden disfunction. I’m not great with editing css or any code but I’m getting this error and have no idea how to fix it. Please any help! (www.sugarysixpack.com)
The ebook videos and ‘meet niki’ pages result in this error.

Error Message

Fatal Error: Call to undefined function encounters_content_nav() in /home2/sugarysi/public_html/wp-content/themes/encounters-lite/page-templates/page-full-width.php on line 39
Description

The Encounters Lite theme code created an error that caused PHP execution to fail.

The code tried to run a function that doesn’t exist (encounters_content_nav()). This type of error is typically caused by a simple typo (is_hom() rather than is_home()), by calling a function provided by a plugin when that plugin is not activated, by calling a function before it is ready (such as calling a function before the code that creates it has run), or by using a function that no longer exists (the function may have been removed from WordPress core or the plugin/theme that previously supplied it).

Solutions

Invalid code modifications can cause this problem. If you have made any modifications to the theme, remove them and try to load the site again.
It is possible that this theme’s code is out of date and that an upgrade is available. Check with the theme’s author to see if an upgrade is available.
There may be a conflict with a plugin running on the site. Try upgrading all the plugins on the site. A plugin conflict can be ruled out by deactivating all the active plugins on the site and checking to see if the error still occurs.
The Encounters Lite theme may not have been fully uploaded. Uploading the theme again could fix the issue. Important: If you do this, you will lose any modifications made to the theme.

My review is for the professional version of Encounters, not the lite version. This is a really good theme! It’s easy enough for someone who’s new to WordPress like myself to figure out what’s what. At the same time, it’s also very stylish and attractive and looks quite professional as if I paid a lot to have it custom made.

Beautiful design with its understated elegance.
