My hosting provided, Backbaud, updated a plugin (Slider Revolution) on my WordPress website on 1/31/20. And days later on 2/8/208 , my homepage, where the slider is located, was totally blank. All other pages on the website worked fine, just the homepage was a blank white screen. It returned a valid HTTP response so my uptime monitor did not report any downtime.
My hosting provider said the homepage looked fine after the plug-in update on 1/31/20.
They are blaming a Cloudflare caching issue. After I cleared my Cloudflare cache, the homepage returned. I have my Browser Cache TTL set to 4 days and my Caching Level is set to Standard.
How can this happen?
