I get this message when I try to open an article with Accordions and Articles Anywhere.
Error message: "RegularLabs\Library\RegEx::replace(): Argument #3 ($string) must be of type string, null given, called in ....\libraries\regularlabs\src\Html.php on line 452"
At first I saw that the articles contained an empty <p> </p> tag on the last line.
However, I removed it in all articles. But the error message persists.
All the extensions are updated to the latest version.
