I’ve got the same problem- can’t upload or delete any plugins through WordPress without the prompt, and then none of my passwords work for it. Also, my Contact 7 forms don’t work- they look like they’re sending, give the success notice, but no email ever gets sent.
I had to set up the server myself using yum. I have no idea what I’m missing. Whatever it is is causing my RAM to climb ever higher all the time.
Please help!
