FOP2 reported that there was an update available, so i clicked on it and it "appears" to have updated ...and it seems to all work just fine, but when I log in as admin, the part that shows the version # is "spinning" constantly. And the bar that shows any licenced plugins is "spinning" (little black dot animation). anyone encounter this?
I have to jump through hoops to reboot the PBX...so i haven't tired that, but i have restarted the FOP2 service and the HTTPD service.

I see the same thing. I've restarted FOP2 and the server itself. Continues after restart and reboot.

I'm running it on FreePBX Distro 10.13.66-21

Coincidentally, I am running same distro.

Seeing same - CentOS7 / ISSABEL 4 / Fop2 2.31.10 (have NOT installed my license - testing new platforms from my old FPBX one) this happens whether embeded in Issabel4 or from outside (read fqdn.tld/fop2/admin) -- I thought it was just my install.
