My sidebar is gone on single.php

ths error interrupts the rendering of your single post:

Fatal error: Call to undefined function yarpp_sql() in /home/bsjovumg/public_html/guiawww.ads-software.com/wp-content/themes/convergence/single.php on line 58

you possibly need to install/activate the ‘yarpp’ plugin (?)

Thanks for your quick response.

I did it but still having the same issue. Once yarpp is active, the sidebar still missing in single.php. I have been trying to deactivate some plugins but no succes at all.

I still see tha same error message at the bottom of the single post of your link.

possibly, the ‘yarpp’ plugin is broken – try to use the latest version and/or replace the plugin with a new upload.

Never add naked calls to Plugin functions in your template.

Change this:

<?php yarpp_sql() ?>

…to this:

<?php
if ( function_exists( 'yarpp_sql' ) ) {
    yarpp_sql();
}
?>

That way, if the function doesn’t exist, you don’t get a fatal error.

Thank you both.

It was the last version of the plugin, anyway I have delete and download a fresh version, activated and still getting the same errors. What I notice now is the admin bar at the top of the page is missing too. I meant there is the space for the bar but no bar at all.

Change this:

<?php yarpp_sql() ?>
…to this:

<?php
if ( function_exists( ‘yarpp_sql’ ) ) {
yarpp_sql();
}
?>

That way, if the function doesn’t exist, you don’t get a fatal error.

Thank you Chip.

Where is the file were I have to change that code ?

In single.php there is only this code refring to yarpp:

$results = $wpdb->get_results(yarpp_sql(array('post'),array()));

Thank you again for your help.

Change this:

$results = $wpdb->get_results(yarpp_sql(array('post'),array()));

…to this:

if ( function_exists( 'yarpp_sql' ) ) {
    $results = $wpdb->get_results(yarpp_sql(array('post'),array()));
}

Thank you chip. Is working now. My sidebar and comments area are back.

Never add naked calls to Plugin functions in your template.

That was on the theme itself. I would try to upgrade the theme ASAP. Authors must be aware of this issuee.

Thank you and thank you both.

Mr Chip Bennett, you are my new lord and master!! I have been battling for a couple of weeks now trying to get the page that displays my individual posts to display correctly. Only today did I notice that the bottom part of the page was not displaying at all from a section ending with:

<div class="col1">
<h2>Related Posts</h2>

I do not know PHP and there was some terribly complex function call to bring up “Related Posts”. I bought my template from TemplateSold so I did not know about YARRP and did not have it active. When I posted the code that seemed to be creating the error:

<?php $results = $wpdb->get_results(yarpp_sql(array('post'),array()));
foreach ( (array) $results as $_post ) :
$_post = get_post($_post->ID);  ?>

I found out about this plug in called YARPP that the function call was looking for. When I activated the plugin my page still wasn’t working but I eventually found this page where you suggested the fix above. It worked like a dream, and now my page is displaying correctly. Thank you so much. You are a god amongst men.
