@Russ I am working on a dev site that had xenbase on it on XF version 1.5. I upgraded it to 2.3 latest, and despite removing the style (as it is not compatible with 2.x) i still have things like base options, eg admin.php?options/groups/base/ that shouldn't exist.
Steps:
ran upgrade.
on 2.3, made new style (plain XF)
made that style default.
deleted all pixel exit related styles via style manager.
There are no addons.
what did i miss? i would assume that option set and others would be gone with the style removal. I do not want the 1.x legacy code out there potentially causing issues.
