Answer 1

首先；在我看来，联系您购买模板的开发人员是更好的方法。

作为您提供的数据，您在两个文件中重新声明名为

sp_button_group_addon

的函数时出现错误

aarontrans/templates/transpro/sppagebuilder/addons/button_group/site.php

和

aarontrans/templates/transpro/sppagebuilder/addons/button_group12/site.php

您可以通过检查函数的

function_exist

或

changing the name

（在这些文件之一中）来解决错误

解决方案1：更改函数名称

我认为这更好，因为该功能似乎被钩住了

AddonParser::addAddon('sp_button_group','sp_button_group_addon_12');
AddonParser::addAddon('sp_button_group_item','sp_button_group_item_addon');

$sppbButtonGroup_margin = '';
function sp_button_group_addon_12($atts, $content){
    global $sppbButtonGroup_margin;

    extract(spAddonAtts(array(
        'alignment' =>'',
        'margin'    =>'',
        'class'     =>''
        ), $atts));

    $sppbButtonGroup_margin = $margin;

    $output  = '<div class="sppb-addon sppb-addon-button-group ' . $alignment . ' ' . $class . '">';
    $output .= '<div class="sppb-addon-content" style="margin:-' . (int) $margin . 'px;">';

    $output .= AddonParser::spDoAddon($content);

    $output .= '</div>';
    $output .= '</div>';

    $sppbButtonGroup_margin = '';

    return $output; 
}

解决方案2：检查函数是否已声明

检查两个文件中的函数是否具有相同的内容，然后让我们忽略其中一个。

AddonParser::addAddon('sp_button_group','sp_button_group_addon');
AddonParser::addAddon('sp_button_group_item','sp_button_group_item_addon');

$sppbButtonGroup_margin = '';
if( !function_exists('sp_button_group_addon') ){

    function sp_button_group_addon($atts, $content){
        global $sppbButtonGroup_margin;
    
        extract(spAddonAtts(array(
            'alignment' =>'',
            'margin'    =>'',
            'class'     =>''
            ), $atts));
    
        $sppbButtonGroup_margin = $margin;
    
        $output  = '<div class="sppb-addon sppb-addon-button-group ' . $alignment . ' ' . $class . '">';
        $output .= '<div class="sppb-addon-content" style="margin:-' . (int) $margin . 'px;">';
    
        $output .= AddonParser::spDoAddon($content);
    
        $output .= '</div>';
        $output .= '</div>';
    
        $sppbButtonGroup_margin = '';
    
        return $output; 
    }
