Hi,
In the HikaMarket configuration, I forced the setting "link_admin_groups".
The setting and code was previously directly in the plugin but a part of the code moved into the vendor class.
For the moment you can add the setting in the HikaMarket configuration (configmarket / market) view :
<tr>
<td class="key"><?php echo JText::_('HIKAM_LINK_VENDOR_GROUP_WITH_ADMIN'); ?></td>
<td><?php
echo JHTML::_('hikaselect.booleanlist', "config[link_admin_groups]",'',$this->config->get('link_admin_groups',0));
?></td>
</tr>
But that code will be in the next release.
Regards,
