I have the following installed on my server: psa 7.5.3-rhel3.build75050506.13 php 4.3.2-25.ent I read in the new features list for Plesk 7.5.4 that the new GuI was built on PHP5. Is that true? So does the upgrade to 7.5.3 include PHP5? If I run the Plesk Updater from the control panel will PHP5 be automatically installed in the control panel update? Thanks.
