first of all, thanks for this great component :-)
I insatalled at my Joomla 6.0.3 and I can just see the images direcly in the images folder. The folder tree on the left side is empty. I can create a folder and see it in other components and by ftp but the new one is also not displayed in the mosaic component.
Any ideas?

Re: Phoca Mosaic - no folder tree
Hmmm, downloaded today from:
https://www.phoca.cz/download/144-phoca ... -component
installed on two different test servers, everything is OK.
Try to see the network tab in e.g. chrome browser (in dev tools) and see the result of response:
index.php?option=com_phocamosaic&task=explorer.getFolderTree&format=json
if there is no json output, maybe some error is rendered before the json output.

(see the preview or response tab)
