Warning regarding class-wp-hook.php

Hello,

I am getting following error in my site.

Warning: call_user_func_array() expects parameter 1 to be a valid callback, no array or string given in D:\xampp\htdocs\MEGABAZAR-WOODMART\wp-includes\class-wp-hook.php on line 288
class=”product-grid-item product without-stars product-no-swatches quick-shop-on quick-view-on woodmart-hover-base col-xs-6 col-sm-6 col-md-4 post-1601 type-product status-publish has-post-thumbnail product_cat-smartphones-tablets instock shipping-taxable product-type-simple” data-loop=”2″ data-id=”1601″>

I deactivated all plugins but the error persists. Then I activated twentyseventeen theme and activating it solved this issue.

Any idea how I can solve this issue? I am attaching my class-wp-hook.php.

Hi,

Sorry, but we didn’t experience this issue before. You need to upload your website to live webserver and provide us your admin and FTP access so we can check why it happens for you.
