This is a large eCommerce site built with WordPress and WooCommerce. An agency I do development work for, Incite Response Marketing, took over maintenance and marketing for the site and I have made a few tweaks and adjustments to the site. The WordPress theme is no longer supported and has been heavily modified over the years, to there are challenges.
It’s expensive to re-theme a site. If you make poor theme selections at the outset it can be prohibitively expensive, but that’s not the case here. The site was built with WooCommerce, a very popular and sound eCommerce platform, recently acquired by Automattic, the company behind WordPress, and used WooCommerce’s default WordPress theme. The default theme at the time, but that was years ago. WordPress changed, WooCommerce changed, and the theme was abandonded because it became easier to develop a new theme instead of upgrading this one. But this clinet had a working Website that they liked, and couldn’t justify the expense of re-theming. So we did (and do) tweaks necessary for the theme to continue to work with current releases of WordPress and WooCommerce.
