Hi globe.editor,
thanks for using MH Magazine lite.
Your problem probably is caused because you have included the class of the modified widgets with the same class name as the original widgets which is causing a conflict.
You can either change the class name for your widgets and include them as new additional widgets or unhook/unregister the original widgets and then hook/register your version of the widgets.
But please notice that we can’t offer help with theme customizations for free as this is beyond regular theme support which is already free for this theme.
