Root category must be an integer value
at line 243 in file classes/helper/HelperTreeCategories.php

238.     }
239. 
240.     public function setRootCategory($value)
241.     {
242.         if (!Validate::isInt($value)) {
243.             throw new PrestaShopException('Root category must be an integer value');
244.         }
245. 
246.         $this->_root_category = $value;
247.         return $this;
248.     }

Prestashop  1.7.4.2

Hi,

Check the category table (DB table using phpMyAdmin OR similar kind of tool) & check whether any category is marked as root OR not? (is_root_category column value should be 1 for any one category).
