When i try to update from the back end, i get this error...

1.0> Checking for latest version
1.1> Connecting to server: codoforum.com ...

: Initiating cURL request

Error: 35: error:14077438SL routinesSL23_GET_SERVER_HELLO:tlsv1 alert internal error
Notice: ob_end_flush(): failed to delete and flush buffer. No buffer to delete or flush in /home/qrcashbw/public_html/admin/modules/system/upgrade.php on line 369

Any idea what this means and how to fix it?

Thanks, Richard

Did you try upgrading it again ? Still getting the same error ?

Yeah I tried it again but it's exactly the same.

Could it be something to do with my server?

May be you can try installing in your localhost?
