I don’t remember from the other threads, did you already fix the permissions in config.php?
'default_permissions' =>
array (
'dir_mode' => 1517,
'file_mode' => 420,
'user' => 'youruser', // you must replace <youruser> with the actual value
'group' => 'yourgroup', // you must replace <yourgroup> with the actual value
),
Then, it might also help to clear any directory from a previous failed upgrade attempt (upload/upgrades/something)
you know?, im trying to upgrade like a test, other suitecrm’s instance, but in the process when the wizard is checking the permissions, users and groups, made a chash on the system… like a timeout finished or something like that…
When finished the wizard showed me on the browser Service unavilable…
this happened this yesterday, and casually i made the same test on a backup’s instance since 7 days and work fine, but i not understand why on the yesterday backup instance not works, maybe for the quantity of files (the wizard have shall check each file… mp3, pdf, jpg)?? or the cache stored very heavy files?
