This problem is happening on WordPress. I had the problem with 2.12 I just upgraded to 2.7.1, everything was fine, I installed a couple of plugins and not I am having horrible problems.
Everytime I try to do something, I get logged off, and have to login 3 or 4 times to get back in. This is a weird problem that has happened with multiple versions.
I just did a search, and apparently this is a well known problem and not just happening with me.
Could this be a bug?
I run another blog with B2evolution software and never have a problem logging into the control panel, nor getting booted out. This is not rocket science and I have a lot investted in my blog. Something must be amiss here. I will try firefox and see what happens.
