Like I said in my previous post, I have done all that. I have enabled cookies and done all the necessary things but still no luck.
Someone suggested to me that the problem could be because I am browsing through a proxy, since I can have access to the admin when using my Samsung Tablet which uses a different network from the one I use to browse the internet. But why would a plugin conflict with my proxy is the very next question on my mind.
I have managed to disable the plugin and now seeing wordpress native login, but when I try to login I get the following error:
ERROR: Cookies are blocked or not supported by your browser. You must enable cookies to use WordPress.
What surprises me is that when using my Samsung Tablet, I can login freely, but when I try logging in using my system I get the error above. I have cleared my browser histoy, cache, cookie, and everything but the problem still persists.
Please help.
