Starlust review for Magic Zoom Plus

I installed this app on Corano theme. It seemed to work well. But after a crawl from Ahrefs I lost 22 top ten pages and 30 positions. Over 500 of my photographs showed sizing errors. This may have been a conflict with another app that I had installed- VF image resizer. With any explanation, it was a huge mistake and set me back months in SEO.
