Can't edit/save on slider/slides, Smart Slider admin area doesn't work

Error:
  • Can't save on slide or slider's settings.
Possible causes:

WordPress

This kind of problem can happen, if there is a wrong plugin installed (or there is a wrong theme file), which makes a JavaScript error and stops every code on your website, or if there is a server limitation. You should check for JavaScript errors like this to try to figure out what is causing the problem. You might see the error message appearing on refreshing the page, but it could happen, that you will only see it when you try to save on your slide/slider or use the option, which doesn't want to work.

Or you could just try to deactivate all your plugins, check it like that to see if one of them is the problem. If one of them will be, then activate a couple of them together, check again and slowly narrow it down which one is the issue.

On rare cases server limitations can cause issues too, and 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 should check for JavaScript errors like this to try to figure out what is causing the problem. You might see the error message appearing on refreshing the page, but it could happen, that you will only see it when you try to save on your slide/slider or use the option, which doesn't want to work.

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. Also you could ask them to check the error log, which could also tell the cause.
