Once I've created my slides, or modify a premium slider, i save the change but they come back as before. Why?
There is no issue like this present in the latest release of our plugin (6.4.), so unfortunately it is most likely a conflict problem on your installation or a server configuration issue.
To start troubleshooting please try to temporary disable other plugins and switch to a default theme to see if that solves the issue.
Please also check the LayerSlider System Status, located on the WP sidebar for any related error message.
I disable the other plugins and i switch to default theme but the problem persists. I have the latest version of the plugin! In the LayerSlider System Status is all green except "WP Debug Mode" is "Disable".
Please set up a temporary WP login for us so we can investigate this problem from the back-end. Make sure to set the message to private so others can't see the login credentials.
