Hi Milos,
I did the upgrade:
from 1.6.0 to 1.6.4 succesfully
from 1.6.4 to 1.6.5 succesfully also, but
from 1.6.5 to 1.7 i get an error "copy failed"
And i have checked the Worning tab and i says:
PHP Upload sizer Bigger than POST size:
The value of the upload_max_filesize in the php.ini file is greater than the post_max_size variable. The post_max_size variable will take precedence here and block requests larger than it. This is generally a server misconfiguration when trying to increase upload sizes. Please increase the upload_max_filesize to at least match the post_max_size variable or vice versa
What to do now?
