Solution for The blob cache is not enabled in this web application error

I have enabled blob cache for this web application as part of the web.config file. See the below code snippet for your reference.

Default code block
< BlobCache location=”C:\BlobCache\14″ path=” \.(gif|jpg|jpeg|jpe|jfif|bmp|dib|tif|tiff|themedbmp|themedcss|themedgif|themedjpg|themedpng|ico|png|wdp|hdp|css|js|asf|avi|flv|m4v|mov|mp3|mp4|mpeg|mpg|rm|rmvb|wma|wmv|ogg|ogv|oga|webm|xap)$” maxSize=”10″ enabled=”false” >

if you read the code block Block cache was diabled enabled=”false” Change the code with enabled=”true” and reboot the application pool to fix this issue.
