I can't update plugins as it says it's at the latest version. https://static.livechatinc.com/8801096/PBFAI2C506/c3178dc389aeb7364e6d7bf9ca54a8e6/WPMU_DEV_Plugins_%E2%80%B9_Dan_Linehans_Bar_%E2%80%94_WordPress.jpg
There is enough space in the server and tried with changing file permission with 777 but no luck. And this is only happening for WPMU Dev plugins. I can install and update wp.org plugins without any issue. Please help!
