The most common reason for this is a broken tab on a tabbed island.
1. Figure out which page has the bad tab island.
2. As you can see in my example below. I have two tabs, "tests tab", and "pte"
- In the SQL table PWPageIslands you will see the two tabs in the Pref String column.
- Notice how there is a | between the tab name and the GUID. That GUID needs to be 32 digits long. If you see one the is not 32 digits long you need to remove it.
- For example, if there is
- You would have to remove "test tab2|e23465f3-~" because the GUID isn't 32 digits long.
