as I don't know if it is an issue or not, I prefer to post here before.

with upload tab, you have following url :

[site_name]/zp-core/admin-upload.php?page=upload&tab=images (jQuery)&uploadtype=jQuery

and

[site_name]/zp-core/admin-upload.php?page=upload&tab=images (http)&uploadtype=http

I don't know if space in url are valide or not

Spaces in urls are generally valid but not within such query urls. So there should be no spaces and the (http) and (jquery) probably either. Probably just a typos somewhere. Best open a ticket.

PS: I changed your forum title :-)

I'm not sure if this issue is related or not. But I went to the upload tab and the http tab from there. I clicked the choose file and selected my image, and I chose an album that was already created.

However it didn't give me the upload button and said I needed add a title for the new folder (which I wasn't trying to do).

Ended up uploading by FTP so I forgot to bug it until now.

all fixed now

Is it me or is the http and jquery in this fix the same upload interface?

Good catch. Fixed now.
