Common installation errors
Upload max filesize
⚠️ Error There was an error loading this file to the server. The uploaded file exceeds the
upload_max_filesize directive in php.ini.
If you can see an error message like this, when you are trying to install Smart Slider, that means that your server has a low
post_max_size limitation. You should contact your server host and ask them to raise these server values for you!
An alternative could be the FTP installation method, but a low upload filesize limitation can cause many issues in the future too, so we rather suggest getting this resolved with your server host.
The filename starts with UNZIP_FIRST
Installing plugin from uploaded file: UNZIP_FIRST_smartslider3-wordpress-PRO-22.214.171.124.zip
Unpacking the package
Installing the plugin
The package could not be installed. No valid plugins were found.
Plugin installation failed.
Go to Plugin Installer
If the Smart Slider installer you're trying starts with UNZIP_FIRST then you need to unzip this file first and use the zip file inside, which name starts like this: smartslider3-wordpress-PRO-, without any UNZIP FIRST text.
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!
