Do you support, or offer help with, modifying themes?
I do not offer any support for modified themes, or support to modify a theme’s internal code. As an individual I simply do not have the time and resources that this would require. In addition to not being able to help each and every customer with customizations, keeping track of each user’s custom code base would be a nightmare. Especially when it comes to theme updates — if a theme needs an update, then I would need to also create a custom update for each user with a custom theme, as to not overwrite their custom code base with the stock theme update.
I do not support custom code inserted into a theme by yourself or a third-party user. Adding custom code to the contents of a theme, whether it be the main content area, the sidebar, through Stacks, etc to a theme is also included in this category.
