Upload & Sell: Off
| p.2 #5 · Warning to those upgrading to WordPress 3.5 |
I upgraded wordpress once a couple years ago, and the whole site went up in flames. So yes, it happens.
(but I also had a backup!)
Something I have learned the hard way:
*Always* back things up before an upgrade - regardless of platform (web site, computer OS, etc.) You never know what might happen. Just because you had trouble-free upgrades in the past does not mean you will never have a catastrophic issue. (You have been warned. ;-))
