Hello,
I use the plesk version 10.4.4 and tonight was an automatic update Panel (MU # 44).
When updating the white screen problem happen again I changed the file "common_func.php3 but still not solved.
Among other times, just changing the file was solving.
This is a system failure and was not resolved until today and now I have several blank screens on the control panel.
Please, I need the support of Parallels for this because every time the problem is occurring and now I'm not getting resolved.
Regards,
Maciel
