Strange, modx-2.2.1-pl seems to have a problem with JS.
The CMS is use less. See attachment.
I changed:
compress_js,
and
compress_css
to 0 on the modx_system_settings table and empty the core/cache folder.
The problem remains the same.
Can anyone please help me?
Problem solved: I uploaded MODx to the server again and run setup. Now it is working. Maybe a file was not really uploaded to the server the first time.
