Common problems
Upload max file size
⚠️ Error
There was an error loading this file to the server. The uploaded file exceeds the upload_max_filesize directive in php.ini.
This error message 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 installation 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 searching 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 by connecting to your website via FTP. You can use the Install from Directory method.
Install from Directory method fails
When the Install from Directory method fails that means that the path you are using (at step 4) is incorrect. In this case you should open up a notepad, write this code in it:
<?php $dir = dirname(__FILE__); echo "<p>Full path to this dir: " . $dir . "</p>"; ?>
Save it down, and rename it for example to path.php
Then upload this file into your website's tmp folder. After this check it in the browser, what does your file write out: http://example.com/tmp/path.php
It will write out the correct path, and that is what you should use (plus the name of our folder).
You should also check if your configuration.php file has this tmp path correctly.
Where is the ftp of my website?
When you purchased your website from the hosting company you have received an email with the ftp account to be able to access its folders and files. That is the account you need, and for example with Filezilla you can access your ftp.
If you are not sure what your ftp account is, contact your server host and ask them for it!
