We have renamed Post Grid plugin to Post Grid Combo
I have been using this plugins for about 6 months and this was working fine since recent update.
I can not change color style, this is showing default ( sky blue ) at the front end.
I am using free version.
Let me know if this can be done on free verstin
I'm not sure which plugin are you talking about. Could you please mention the plugin name? and also share some screenshots so that we can identify the issue.
