PHP Warning: Undefined array key “titleWrapper”

Hello,

Thank you for your query and we are so sorry about the trouble this must have caused.

We have already 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 and please do not hesitate to let us know if you need our assistance with anything else.

Hello,

You edit the plugin file from WP Dashboard > Plugins > Plugin File Editor and select the file mentioned by my colleague to change the code.

Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.

Hello,

In that case, you need to use the FTP access provided by the hosting provider or the administration panel on your server to locate the file and make the necessary changes.

Thank you.
