Can't save on slide or slider

Error:
  • Can't save on slide or slider's settings.
If this is only happening on video slides, then check out this documention instead.
Possible causes:

WordPress

This can happen, if you have a wrong Plugin installed, but this can also happen because of your theme, or due to a server limitation. You could try to deactivate your plugins, change the theme. If it's due to a server limitation, you could try to turn on the "Send as file" option at the global settings. Usually servers are limiting the size of what you are trying to save, so if you managed to save so far, just you made your slider bigger, then this will be your problem, and you should contact your server host to increase the memory_limit on your server. Also you could ask them to check the error log, which could also tell the cause.

Joomla

This can happen, if you have a wrong extension installed. You could try to go to your Extensions -> Plugins, filter out the "system" plugins, and unpublish them (except our "Nextend2 Library" and "Nextend Smart Slider 3" plugins). If it's due to a server limitation, you could try to turn on the "Send as file" option at the global settings. Usually servers are limiting the size of what you are trying to save, so if you managed to save so far, just you made your slider bigger, then this will be your problem, and you should contact your server host to increase the memory_limit on your server.
