I want to upgrade PHP version whis is 4.3.2 to 4.3.3 How can i do this? My service provider said that upgrade your Plesk version, 7.5.4 to 8.0.1. But i couldn't success to upgrade. I got an error that said "gunzip can not read header files". Autoinstaller downloaded some files, but when tried to unpack archives of plesk 8.0.1, this error occured. Is there another way to upgrade my php version without upgrading Plesk? My server OS is RedHat_EL_3 with Plesk 7.5.4 Reloaded. Thank you.
