how can i solve this issue Warning: Undefined array key “titleWrapper” in

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.

We have identified this issue and reported it to our development team. We will include a fix in a future update of the plugin.

For now, please replace the code on line 103 of this specific file seo-by-rank-math/includes/modules/schema/blocks/toc/class-block-toc.php with the code below:

$title_wrapper = isset( $parsed_block['attrs']['titleWrapper'] ) && in_array( $parsed_block['attrs']['titleWrapper'], $allowed_tags, true ) ? $parsed_block['attrs']['titleWrapper'] : 'h2';

That notice should go away.

Hope that helps.

Thank you.

Hello,

This will not expose any sensitive information.

Having said that, this was fixed internally and the improved code with this fix will be released in the upcoming release of the Free plugin.

Thank you.

Hello,

You can edit the plugin files in WP Dashboard > Plugins > Plugin File Editor and edit the file mentioned by my colleague. If you are not sure, 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.
