|

| 191 | track of posts and feeds will cause problems such as duplicate posts and broken

| 192 | templates if we were to continue without the upgrade.</p>

| 194 | <p>Note that most of FeedWordPress's functionality is temporarily disabled

| 196 | working as normal again once the upgrade is complete. There's extraordinarily
|
|---|
| 197 | little chance of any damage as the result of the upgrade, but if you're paranoid
|
|---|
| 198 | like me you may want to back up your database before you proceed.</p>
