Hey everyone. So a few users have been experiencing upgrade issues with the new version of Easing Slider "Lite". What appears to be happening is that the plugin is de-activating after the upgrade process. Once activated, the plugin appears to be reset and users appear lost there slideshow settings.
This was occurring because the main plugin file was changed from 'easingslider.php', to 'easingsliderlite.php'. This small detail was actually causing no problems at all on my own WordPress installs, of which I tested 7. However, for some users this caused the plugin to automatically deactivate, thus hampering the upgrade process that would import your old slides; hence the impression that everything had been deleted.
v184.108.40.206 of Easing Slider "Lite" has revoked this automatic process that was subject to failing. Instead, we've chosen to go with a manual process in the form of a button on the 'Edit Slideshow' page. Once you've upgraded from v1.2.1, you'll need to press this button to import your own settings. It's not ideal, but it works.
I've taken a quick screencast below of myself following the upgrade procedure. It's actually very simple, and very familiar. Again, just be sure you import your old settings afterwards. That's it.
On a side note, Easing Slider "Lite" v2.x doesn't actually delete your old settings, so if you decide to downgrade back to v1.2.1 your old settings will remain in-tact, as they were before.
Lastly, for most users the upgrade process has actually been going fine, so don't be alarmed or deterred from upgrading if you haven't already. Although I'm unaware of the reason why the upgrade procedure seems to differ for some WordPress installs (probably due to their hosting setup), it looks like it has (hopefully) been resolved in taking an alternative approach.
