 I have checked line 345 in the Data.php file

foreach ($this->getChildCategories($category) as $childCategory) {
            $this->getCategoryOptions($childCategory, $options, $level, $htmlPrefix);

Any ideas on why this is happening

Magento 2.2.3 Theme Porto module-core up to date

I'm getting the same issue. Disabling Mageplaza search and clearing cache removed the problem for me but then i cant use the Extension. Re-enabling Mageplaza search just brings the problem back. I initially had an issue installing a theme as I already had the core installed as I was using SMTP by Mageplaza. The theme tried to install Mageplaza core initially but it was already present so Install failed. Removing Mageplaza core folders in app and vendor then tidying composer  meant i was able to install my new theme, but then this problem. For ref I will be raising the issue with Mageplaza.

Hello @andrew_woodward

As we can see at the line no. 345, There is a loop of the child categories.

Probably there are no child categories in the category which you are trying to open in your browser.

You have to add the if condition to check if this category has the child categories or not.

You can do as given below.

if ($this->getChildCategories($category)) {
    foreach ($this->getChildCategories($category) as $childCategory) {
        $this->getCategoryOptions($childCategory, $options, $level, $htmlPrefix);
    }
}

Yeah

I had a similar error for smtp and to resolve it I opted to switch to magepal smtp.

But for Mageplaza_search I still haven't found a replacement.
