Sorry about this if dupplicate topic, but I checked all previous question and didn't see any answer for me.
I'm using Wp 9.1 and have many plugin, recent I didnt see wordpress plugin not check new version. For example, the plugin: XML Generator now is 4.0.6, and my plugin is 4.0.4 But when I check update core, it say: " all plugins are up to date"???
Please help me to fix this? Thanks in advance. Andy
