An error of type E_ERROR was caused in line 342

Hello,

Thank you for contacting Rank Math and bringing your concern to our attention. I’m sorry for any inconvenience this issue may have caused you.

Could you please confirm if you have already increased the PHP limit to these values?

PHP Memory Limit: 512M
PHP time limit: 120

If the issue still persists, we might need to take a closer look at the settings. Please edit the first post on this ticket and include your WordPress & FTP logins in the designated Sensitive Data section.

Please do take a complete backup of your website before sharing the information with us.

It is completely secure and only our support staff has access to that section. If you want, you can use the below plugin to generate a temporary login URL to your website and share that with us instead:

You can use the above plugin in conjunction with the WP Security Audit Log to monitor what changes our staff might make on your website (if any):

We really look forward to helping you.

Thank you.

Hello,

Thank you so much for sharing the login information for us to further check the issue.

Before we further troubleshoot the issue, can you also increase your PHP “Max input time” to at least 250.

Please note that Rank Math needs to process 46K pages which Rank Math may not be able to handle due to the given resources from the server.

Let us know how that goes.

Looking forward to helping you.

Hello,

Looks like your site’s memory is getting exhausted as there are more than 40k pages. I have logged this as a bug and our Development team will further work on it to improve the query. Please allow us some time to test and release a fix. For now, to fix the issue on your site I have added the following code to your theme’s functions.php file:

add_filter( 'manage_page_posts_columns', function( $columns ) {
	if ( isset( $columns['rank_math_seo_details'] ) ) {
		unset( $columns['rank_math_seo_details'] );
	}

	return $columns;
}, 12 );

Basically, this code will remove the SEO details column and it will also prevent the site from executing the query due to which the PHP memory is getting exhausted. Please keep this code till we fix this issue in the plugin.

In the meantime, if you need any other assistance, please feel free to let us know. We are here to help.

Thank you.

Hello,

It seems that you have missed our developer’s reply above.

Please follow the steps in the meantime. We will keep you posted once a fix is already available to download.

Meanwhile, please don’t hesitate to contact us anytime if you have other questions to assist you further.

Looking forward to helping you.

Thank you.

Hello,

The filter code should only focus on unsetting the post column on your post list page. You can go ahead and use the filter.

If you are not sure, you may wait for our future plugin update with regards to this fix.

Looking forward to helping you.
