Joomla! Forum - community, help and support

Hello,

I am a Joomla beginner and I would need some information about updating the 2.5.14 version.
When I start up the updating process I get an error message: The achive file is corrupt, truncated...
While trying to do the installation from the Extension Manager, I have another error message.

Would you have any suggestions for these kind of issues?
How could I do, in the end, the update?

Thank you in advance,
Cosmina

There are a couple of different methods for updating. Try the methods on: http://docs.joomla.org/J2.5:Upgrading_f ... ng_version to see if they can help you resolve the issue with your site.
