Phoca Extensions use standard Joomla! filesystem methods. Folders in Phoca Extensions are created with help of JFolder method and permissions are set to 755. As many hacking robots can write malignant code to folders with permissions set to 777 without any problems, creating of folders with such permissions (777) was deprecated.
Using 755 permissons can be problematic on some servers as they only allow to write files and folders into folders with permissions set to 777. This can be very dangerous. If you have problem with permissions on your server, try to enable FTP layer in your Joomla! Global Configuration. (The FTP layer should be enabled before installing Phoca Extensions, so created folders will have the same ownership as your FTP account).
If enabling or disabling FTP layer didn't help, try to ask your webhosting provider to check permissions and ownership settings on your server.
In worst case you can test to set the permissions of folders to 777.
Changing permissions in Phoca Gallery
- Using JFile method - Joomla! framework's JFile method can create thumbnails with help of FTP layer. If you have enabled FTP layer and folders have ownership of your FTP account, you should enable this parameter (JFile Thumbnail Creation set to Yes)
- Not using JFile method - If you are not using FTP layer, try to disable this parameter, so thumbnails can be created by server script (with server script ownership).
