Google webmaster tool show cache result but website show cache error

I recently check my website cache status before a couple of days. It was completely cached but after some days when I again check cache so it was showig error.

I do fix the error & did request to check my website page on Google webmaster tool. The request was completed but my website pages wasn’t cache. Even I status in Webmaster tool is complete but still website pages are deindex.!

Disable the cache plugin if you have installed any. Or contact the hosting provider to clear your website cache and re-generate your website sitemap with the SEO plugin. Remember to submit link into google webmaster so that your website keeps crawling.
