Hello,
after an update from Joomla 3.10.11 to Joomla 5.0.2, Quick Index is no longer displayed. I add QI to a module position via a module and "Prepare content" is activated.

Placing {index} directly in the article works.

An example page of my website is: www.kreuzfahrt-praxis.de/joomla5/kreuzfahrt-ziele/doha-katar
There is a button with the name "table of contents", where the table of contents should appear with one click

On my old Jooml 3 Site it works fine:
www.kreuzfahrt-praxis.de/kreuzfahrt-ziele/doha-katar


Do you have an idea what the problem could be?

I had already read the article and tried a bit, but without success. What is the ideal order for the regularlabs plugins?

No i dont use Auto Index
