My developer with questionable code practices modified a few core files, We tried to integrate a new theme and a few blocks are posing a problem.
The site has been running for over 6 months and I don't want to waste all the SEO efforts.
My development team is suggesting 3 options
- New instance of magento altogether
- Custom theme developemnt
- Upgrading magento version from 1.9.1 to 1.9.3
