ssh to your server and check if the permissions of /tmp are set to 777. If not, the cpanel version of php can not be executed. Chmod /tmp to 777.

-- If this doesn't help, do a
locate php.ini

if the results do not contain
/usr/local/cpanel/3rdparty/etc/php.ini
/usr/local/cpanel/3rdparty/lib/php.ini

then you do not have the cpanel version of php installed. Perform a cpanel update to fix (a cpanel update can be done using WHM).

-- Also make sure that the Fantastico admin account has enough free space (quota). This should be better set to "unlimited" anyway.

-- Also check if your hard disk is full or if the /tmp partition is full.

Not exactly sure why you are posting answers to questions that are not being asked. Some of the answers are less than fully factual. In this case, and I would be happy to be corrected, setting /tmp to 777 is not a good idea. At a minimum /tmp should have the sticky bit set.

the problem is that with latest edge php stopped to work inside cpanel
