Several problems in the new version 3

-- HikaShop version -- : 3.0.0

Hi noticed several problems in version 3.
The first problem is when I try to Convert cart in wishlist displays the following error (legacy) : Access forbidden.
The second problem is the module contents example Related products - there are no buttons function recently reviewed.
The third problem is no longer displayed buttons on facebook for likes or sharing.

Hi just specify whether talking about the same button
1 question -

1. Hi after the update gives me the following error: HTTP ERROR 500
2. I found where the problem.

In the new version code is (plugins/system/hikashopsocial/hikashopsocial.php):
if(empty($plugin->params)){
$plugin->params = 'fb-like';
}
$html .= '<div class="'.$plugin->params.'" data-href="'.$url.'" '.implode(' ', $url_options).'></div>';
}

if it replaces the code: $html .= '<div class="'.$plugin->params.'" data-href="'.$url.'" '.implode(' ', $url_options).'></div>';
with that of version 2.6.4: $html .= '<div class="fb-like" data-href="'.$url.'" '.implode(' ', $url_options).'></div>';

Buttons are available.

1. syntax error, unexpected ''showcart'' (T_CONSTANT_ENCAPSED_STRING), expecting ')'
2. I meant that if back button code from version 2.6.4 (plugins/system/hikashopsocial/hikashopsocial.php) - no problems with them.
(If you change lines from 365 to 369 of the new version:

if(empty($plugin->params['fb_type'])){
				$plugin->params['fb_type'] = 'fb-like';
			}
			$html .= '<div class="'.$plugin->params['fb_type'].'" data-href="'.$url.'" '.implode(' ', $url_options).'></div>';
		}

$html .= '<div class="fb-like" data-href="'.$url.'" '.implode(' ', $url_options).'></div>';

<span class="hikashop_social_fb"><div class="5" data-href="https://andronika.net/index.php/games/product/1-anno-2070" data-layout="button_count" data-show-faces="false" data-font="arial" data-send="true"></div></span>

Thank now everything is fine. I continue to test the new version and if I find something it will write.
