Hi, the pro plugin works fine, but after i change the server i'he a problem with all images, "There was a problem rendering your image gallery. Please make sure that the folder you are using in the Simple Image Gallery Pro plugin tags exists and contains valid image files." i try everithing but still not working. what i can do?

Make sure you have the correct permission for files/ folders in your new installation.

Please install Admin Tools from www.akeebabackup.com/downloads/admin-tools.html 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

Admin Tools can fix any read/write "file" permissions on your site, to what they should be.

Also double check to see if you have the correct paths to your /tmp /logs folders.
