Go to your Plugins list and deactivate and delete your current Smart Slider 3 installation. Don't worry, your sliders will stay!

If you would have a problem, where you don't even see Smart Slider 3 on your Plugins list, you should delete its folder with everything in it from FTP. We suggest making a backup, to be sure you are deleting the correct folder. You can find Smart Slider 3's folders on the following locations:

• Free version: \wp-content\plugins\smart-slider-3\
• Pro version: \wp-content\plugins\nextend-smart-slider3-pro\

Common error messages

1

Unable to copy

The problem on your server will be, that the files and folders have different permissions. You could try to change all permissions on your FTP (for example with Filezilla), but usually the real issue is, that the services are running under different owners. For example:

Ftp server runs with owner: xy
Apache runs with owner: z

If you install new plugin with WordPress upload, the plugin's files will have the owner 'xy' as Apache creates them. In this case you can update this plugin from WordPress.

Then you choose to upload a new plugin with FTP, you place the files into the right folder, but those files will be owned by "z" and when you try to update these files from WordPress, the Apache process with owner "xy" might not have permission to write "z"s files.

Solution

Send this to your server host: ls -lia. This will list out the files and folders from the current folder. On this image ish is the owner and ish is the group too:

When you know the owner and group, you could try to run the following command. It will recursively set the owner and the group for the files and folders of the current folder:

xy is the user and www is the group in this example:
chown -R xy:www ./
Then update permission on those files. This call is also recursive:
chmod -R 755 ./

Upload max filesize

If you can see an error message like this when you are trying to install Smart Slider, that means that your server has a limitation, that files that are larger than the value defined in the php.ini (or .htaccess file) is smaller than the Smart Slider's intallation package. The limitation on most cases is below 2Mb.

If you would have access to your php.ini file, you could modify this value by seaching for the upload_max_filesize or post_max_size words.

If you wouldn't have access to that file, you can still install the slider with FTP installation method.
