    Technical Support

    We provide support directly related to issues with install or operation of the plugin, including clashes with other plugins or themes, at no extra charge. During beta testing we advise use of a staging site. We are also available to assist with related matters such as content tagging/categorizing, setup of ACF custom fields, custom post types, site styling, synonym setup, dark mode, etc. that affect facets, filters, search performance or appearance. This work is generally quoted on a daily rate basis. Please ask for a quote or assistance.

    Code and styling assistance

    Although we aim for a ‘no code’ experience, sites that need to match existing content style, or need search results that include meta data from fields or published date formatting may require knowledge of  HTML and CSS. We are happy to assist at no extra charge, however if you need us to carry out work that is likely to require more than  a few minutes, please ask for a quote.
