Strange error code appearing in empty sub categories

Ideally, you need to know what you’ve done to alter that, as I’ve not come across it with a vanilla install of wordpress before.

You should, take a backup of your site, wamp/lamp it and work on the issue. But in the mean time on your live site you can put in:

error_reporting(0);

Refer to: https://php.net/manual/en/function.error-reporting.php

However like I said, go local and see whats been altered in your site from the original pages?

To be honest I dont understand PHP all to well so I know I havent done anything within the query-php include file. In fact when I found the file in Cpanel file manager it says the file was last updated on the 29th of December.

Here’s the code I think the error is refering to with line 2746 beginning with foreach.

// Always sanitize
		foreach ( $this->posts as $i => $post ) {
			$this->posts[$i] = sanitize_post( $post, 'raw' );

As Ive no idea what I’m looking at and dont understand the code I have no idea how to resolve this!

Do you have any further advice?

Is there anyway of testing plugins to see if they are causing the problem?

try:

– deactivating all plugins to see if this resolves the problem? If this works, re-activate the plugins one by one until you find the problematic plugin(s).
