I am currently running WordPress 2.7.1. About a week or so ago, I began noticing that I am no longer receiving update notifications when a new version of a plugin is available.
I have already tried de-activating/deleting/reinstalling plugins, but it did not help. Currently, I am running the following plugins:
Daily Top 10 Posts
Datafeedr Random Ads Plugin
DISQUS Comment System
Get Custom Field Values
WP Page Numbers
WP Super Cache
Any ideas? Any and all help would be greatly appreciated!
