Hi bonedriven,

looks like a cookie issue to me. Instead of turning to a different browser, you may as well give a "private tab" a chance to see if that "fixes" the issue.

If so, it could be a timing issue, i.e. the cookie(s) reference a session that has expired. Logging off and on again (i.e. in a different tab) may already re-create a confirmed session so that reloading the original page might work again.
