interference with WP Plugin Manager plugin.

Hello
I am using your plugin and there is a interference with WP Plugin Manager plugin!
That mean when I enable your plugin, The WP Plugin Manager plugin dosenot work!
for example both of the plugins are enabled and I deactived layerslider plugin for this page with the WP Plugin Manager plugin, but it is not worked so layerslider is being actived now, but if I deactived the LiteSpeed plugin, layerslider would be deactived for this page!
