Hello,
I migrated my site to Joomla 4. Before I did it, I deactivated the j51_juliet Template for Joomla 3. The migration went well. The site works with Cassiopeia-Template. I installed j51_juliet Template for Joomla 4 and activated the template again.

I got the error: 500 - behavior::caption not found

I went to: /templates/j51_juliet/html/com_content/article/default.php and deleted the row: JHtml::_('behavior.caption');
(the overwrite is not done by myself, It came with the template).

Now the site is working with the following error-messages:
Notice: Trying to access array offset on value of type bool in /home/.../templates/j51_juliet/inc/style.php on line 165
Notice: Trying to access array offset on value of type bool in /home/.../templates/j51_juliet/inc/style.php on line 166
Notice: Trying to access array offset on value of type bool in /home/.../templates/j51_juliet/inc/style.php on line 167

Is there a bug in j51_juliet Template Joomla 4 ?
Or did I do something wrong updating the site?

Thanks for your help.

Pascale
