Hello.

Sorry for the delay.
Please could you check if this is still happening in version 2.0.1?
Thanks

Yes I am using version 2.01. About 1000-1500 such error entries are generated per day. Automatic updating is turned on.
The wp version number is 5.7

I am seeing this error in my logs as well…WP version 5.7 and plugin version 2.0.1

PHP Warning: Invalid argument supplied for foreach() in /var/www/wordpress/wp-content/plugins/www-xml-sitemap-generator-org/code/renderers/xmlRenderer.php on line 94

Thank you for confirming this error. This already proves that this is not a unique error. Now it would only be good if the repair was done.

Hello,
i am using the plugin too.
I also confirm on my site I get many identical errors in my error_log_php.

Hi, I’ve just installed the plugin and am getting the same error. You can see it in the XML here.

Hello,

you can hotfix the file wp-content/plugins/www-xml-sitemap-generator-org/code/renderers/xmlRenderer.php line 94 – function renderImages just add isset condition

View post on imgur.com

private function renderImages($images)
		{
			if (isset($images)) {
			
				foreach( $images as $image ) 
				{
					echo '<image:image>'  ;
					echo '<image:loc>'  . $image->location . '</image:loc>';
					if (!empty($image->caption)) {echo '<image:caption>' . $image->caption . '</image:caption>';}
					if (!empty($image->title)) {  echo '<image:title>' . $image->title . '</image:title>';}
					echo "</image:image>\n" ;	
				}

			}
		}
