this solution I also found, but does not always work ... I tried to make archives with windows-packer and with WinZip. once - works, other times - no. with packer under windows - don't works 100%

the main problem is that, if I want to change the gallery (delete old and install new gallery-images), or clear the cache, or cache time in the plugin is expired - just shows the error.

Try searching for the error in Google and you will see how many Site's have the same problem ;)

Pm me access to your backend please.

I've already sent you the access data

I have just upload a zip folder without problem...
Check your Test article please...

Hello I was using iamge gallery on local host, working well.  I moved my site to a host server and now I am getting an error:
jfolder:files: path is not a folder. Path:/home/ecklereng/public_html/images/projects/(foldername)/.

I have change the paths in the plugin configuration in different ways to match the new server, but still no luck.  Can you please tell me how the path needs to be configured.
Thank you for your time

Check your permissions other than your paths.
