Cannot save modifications to module using Joomla Admin interface

Hello again Jackie,

Here is the issue I was describing.

MAC OS 15.6.1
MAMP PRO 7.2.11
Joomla! 6
PhP 8.4.1
MySQL 8 (8.0.40 for macos12.7 on arm64)

If I try to modify one of the jux_timeline_pro modules using the Joomla! admin interface, it fails. The module does not check in on "Save" or "Save and Close". Reopening the module shows the change was not saved.

If I alter the SQL directly (in the video I use phpMyAdmin5), that change shows up in the module component in the Joomla! admin.

Evidently there is something going on here, but I am not getting any errors displayed for this.

I have uploaded a video to drive.google.com/drive/folders/1NEL9YJWu...X830f?usp=drive_link

I will repeat the process and then add the debug log for it.

Best regards, Al

I turned on debug and error reporting to maximum, but all I am seeing in the browser are the warnings about

```
Warning
: Undefined property: stdClass::$autostart in
/Applications/MAMP/htdocs/joomla6/plugins/system/guidedtours/src/Extension/GuidedTours.php
on line
199
```

I fished around for other logs in the installation. The only ones that look relevant are the php_error logs in the MAMP log directory. Have a look ...

Thanks, Al
