Hi,
After conducting tests, we've discovered that the /images/
folder on your site contains an excessive number of files. This is causing the media manager to freeze, and as a result, the JA Blockk template manager is also affected.
To resolve this, please think about removing any unused images or organizing them into subfolders to get less displaying file number.
You can replicate the same issue when viewing the media section: administrator/index.php?option=com_media&path=local-images:/
Regards
