 * Good morning,
    I found this console error on my browser console in the backoffice
   area of WordPress:
 * `Uncaught TypeError: Cannot read properties of null (reading 'getElementsByTagName')`
 * The stacktrace tells me that the error starts from this point:
 * `easy-table-of-contents/assets/js/admin.js`
 * Can you check this please? On WordPress version minor of 6 this is the cause 
   of a fatal javascript error that block their execution. Thank you!
