First thank you in advance for your help.
I just migrated from a Asterisk 1.4 system running FreePBX 126.96.36.199 to an Asterisk 1.8 system running 188.8.131.52. Everything was working including OSS Endpoint Manager after the migration. After upgrading and confirming everything working I upgraded to Freepbx to 184.108.40.206. Everything is still working except OSS is giving me a blank screen on “Advanced Configuration” and “Template Manager” and says I need to confirm my settings under advanced config. I tried uninstalling and reinstalling using module admin, but I still have the same problem. The installed version of OSS is 220.127.116.11. Any help would be greatly appreciated.
