Hi
I've seen many entries on this topic and none of the suggestions helped me
I bought SIG pro 2.5.7 and I am using it on Joomla 2.5.4

Every time I upload a zip file, I get the error:
Unknown Archive type
Gallery upload error. Cannot extract archive

The location folder that I set in the plugin is /media/k2/galleries/

I set the folder to 777

No motools nor jquery for Popup engine for image galleries

I modified the class.upload.php file to use
$this->file_src_mime = mime_content_type($this->file_src_name);
instead of
$this->file_src_mime = mime_content_type($this->file_src_pathname);

I added zip, ZIP to the Legal Extensions (File Types) in Media Manager content options

Any other suggestions?
Thank you

Please install Admin Tools from www.akeebabackup.com/ in order to fix your permissions as they should be

and then reinstall the extension.

Right permissions on all joomla sites:
755 for folders
644 for files

Thank you for your reply.
I installed and ran the Fx Permissions.

I tried to upload a zip file to the K2 image gallery and I got the same error message.

Anything else you think may be wrong?

Thank you

How did you made the zip file?

Hi Katia

Thank you for looking into it.
Upgrading the version of K2 solved the problem

Did you use Admin Tools?
Please do, and if the problem remains pm access to your super admin in order to check it out.

used Admin tools to fix permissions, still the same.

Your issue has been solved. You had wrong path for your images in SIG PRO settings.

Hi,

So what is the default path for the images in the settings of SIG Pro?

Kind regards,
