Not sure what has happened but I cannot access the adm-index.php page any longer. Nothing to my knowledge has changed and it has worked for months. It was running 5.13 using VB
and VBPortal when the problem occured. I tried uploading a backup copy of the adm-index.php file (v5.13) and tried that without success. I then downloaded PP v5.2 uploaded the files and ran the upgrade with success but still can't see the adm-index.php page. All that appears is the frame bar on the left but everything else is blank. The rest of the site is fine.
