Hi Peter,

We have added some extra tabs to the modules in a Joomla 4 installation by using the params.xml option added in PR: github.com/joomla/joomla-cms/pull/23577

The problem now is that the module layout is messed up. We fixed it in our installation by changing the following file:

\administrator\components\com_advancedmodules\layouts\joomla\edit

@ line: 199
- echo JHtml::_('bootstrap.addTab', $tabName, 'attrib-' . $name, $label);
+ echo JHtml::_('uitab.addTab', $tabName, 'attrib-' . $name, $label);

@ line: 137
- echo JHtml::_('bootstrap.endTab');
+ echo JHtml::_('uitab.endTab')

Can you take a look if you can fix this?

Regards

Thanks Peter. I'll have a look!
