Hi,
that code can’t be removed directly from the plugin files unless you are ok removing it after every update.
The only way to proceed would be:
1st remove tabs completely with this in functions.php:
remove_action('geodir_details_main_content', 'geodir_show_detail_page_tabs', 60);
Copy function geodir_show_detail_page_tabs from custom_functions.php file line 1381 to 1692
Paste it in your functions.php file and rename it function my my_geodir_show_detail_page_tabs
Delete or comment out the code for mobile tabs menu:
<div id="geodir-tab-mobile-menu" >
<i class="fa fa-bars"></i>
<span class="geodir-mobile-active-tab"><?php echo $active_tab_name;?></span>
<i class="fa fa-sort-desc"></i>
</div>
Add back your new function with altered code.
add_action('geodir_details_main_content', 'my_geodir_show_detail_page_tabs', 60);
Thanks
