Hi, I've recently discovered a very weird issue with redis Object Cache and WordPress's wp_cache_set() function. So, I'm explaining the problem here: As a WordPress dev myself, I've figured this issue first on my own WordPress plugin called WP Server Stats. Now as per WordPress best coding practices, I've used the wp_cache_set() function to keep valuable things in cache instead of re-quering them every time. Now it works fine on all server but on my main site where I use centminmod + redis object cache + redis front end cache, I saw that the fields that I was using with wp_cache_set is showing as blank: but it should be look like this: Hope you see the difference. Also on the other day I tried installing EWWW Image Optimizer Cloud on my server and after installing the plugin I was unable deactivate or delete it from my wp admin section. Also any changes I made to the plugin settings wasn't getting saved either. It was just keep reverting back to the initial stage. So, after I had a long discussion with Shane (author of EWWW), he said it might be causing due to the object cache. So, I tried disabling it temporarily and everything went back to normal. I can see my plugin working fine, EWWW Cloud working fine. All good. So, after I configured the EWWW, I again turn the redis object cache back on. To make sure my site remains fast. The reason I'm reposting this to you in hope you can find the problem behind it and fix it in upcoming v0.9 stable release. BTW, when v0.9stable is coming out?
