Issues after installation or update

Can't install or update Smart Slider, receiving a PCLZIP_ERR_BAD_FORMAT error message.
If you get this error message by using a zip file or by updating the slider, then your server's unzipping program is outdated or it has an error, and it's not able to unzip our zip file.
If you used a zip file, it also could be, that during downloading our zip file something bad happened, and your download didn't worked, producing a zip file with an error. To make sure your zip file doesn't have an error, just try to unzip it into your computer. If that works, the server's unzipping should work as well.
You should either contact your server host to resolve this error at their end or use the FTP installation/updating method, where you are unzipping the zip file manually, so your server doesn't have to do it.
You can find instructions in these articles on how to perform an FTP installation on WordPress and on Joomla. If you use WordPress and the update occurs before an update, make sure to delete the old version of Smart Slider first. Your sliders will stay!
PHP Fatal error
- Fatal error: Class 'N2PluginBase' not found
- Fatal error: Class 'N2CacheImage' not found
The problem is caused by that installing/updating your Smart Slider 3 didn't worked, some of the files are missing probably because of a server issue. A reinstallation (which is the same as the alternative update) would solve the problem!
TypeError: N2Classes.NextendAnimationManager is not a constructor
The problem is caused by that updating your Smart Slider 3 didn't worked, some of the previous files are still used probably because of a server issue. A reinstallation (which is the same, as the alternative update) would solve the problem!
