If you're using a RAM cache instead of a disk cache (SSD users), you will need to temporarily disable the RAM cache in order to update your access privileges. If you followed some instructions similar to the ones below when setting up (I use firefox), then try disabling RAM cache (the opposite of the below instructions, if none of this sounds familiar to you, then check for login issues elsewhere):

Firefox
Since SSD's have limited write-cycles, Firefox's behavior of writing cache files to disk is not good. We can force Firefox to write the data to RAM instead by doing the following:

* Type about :config into the address bar and press enter.
* Set the value of browser.cache.disk.enable to false.
* Create a new integer value named disk.cache.memory.capacity and set its value to 32768 (for 32MB), 65536 (for 64MB), or 131072 (for 128MB).
* Restart Firefox.

This will apply to Firefox on any operating system. You will notice increased RAM usage from the program, so if you're low on RAM, I recommend waiting on this one.

It took me a couple days (and a bit of hair pulling) to figure out what was going wrong.

Thanks for the info nako! I'll sticky this.

When I got my access changed, I had to log out and back in on any computers I was regularily logged on with, and that took care of it (was Firefox 3.5).
