WordPress has just released version 4.5 – and with it some nice changes but also some things that break old version of many many plugins. In order to make sure that all of your plugins keep working, make sure to update them as well.
We have just released MP Stacks 220.127.116.11 to go along with the WordPress 4.5 release and it fixes all of the bugs that were introduced by the changes in WordPress 4.5. For those interested, mostly the bugs were related to an update they did to ‘jQuery’.
Regardless, you can update everything all together and you shouldn’t run into any issues at all 🙂
