PHP8 issue

[sparkktv]

Testing PHP 8 in my localhost using MAMP. And running the latest version of Helix Ultimate and Helix Ultimate Template on Joomla 4.1.5. When I use PHP 8, it get the error 0
mb_strpos(): Argument #3 ($offset) must be contained in argument #1 ($haystack)
on every page of my site, but if I downgrade back to PHP 7.4 then the site works without issues. It is indeed a Helix issue as I switched over the the Joomla 4 default template Cassiopeia template and the site worked fine in PHP8.
I'm just wondering when this will be fixed because the release notes say the latest version has PHP8 support but this doesn't seem to be the case.

Here is the call stack... It is related to Widgetkit, however it only occurs when using a Helix Ultimate template. I tested with J4 default template Cassiopeia & Joomlart T4 Framework and the error does not occur, so it is something in Helix Framework causing the error.

Found the issue, you can close this. It's now working. It was a single widgetkit module causing the issue and it was due to a typo on my end.
