My Plesk Control Panel recently started acting weird after an update from 7.5.2 to 7.5.4 It looks as though the upgrade went ok (no errors) but whenever I try to complete an action (say adding a domain) I get an html page filled with Binary Garbage characters. If you look at the source the very first line is #!/usr/local/psa/admin/bin/php then followed by the binary characters. I'm wondering if Plesk uses a binary loader like IonCube or something? When I do a php -v on the Plesk php it tells me version 5.04 is now installed and that's it. On the systems php (/usr/bin/php) a -v tells me it's at version 4.4 with IonCube loader installed. I have posted recently with this problem but doesn't seem anyone recognizes this. Perhaps someone who knows how the Plesk Control panel php works could shed some light for me. Everything is still functional and working on the server, it's just the Control Panel that won't let me complete any actions. Thanks in advance for any help and time spent on this.
