Done button in Text Data text-editor not appearing correctly
Summary
After the user upgrades their Confluence from v5.6 to v6.10.2, the Text Data macro does not display the Done button correctly and no scroll bar is available, hence user is unable to save changes.
Environment
Confluence v6.10.2
Scaffolding v8.19.3
Cause
This issue is caused by a conflict with another app called ThemeBuilder.
Workaround
Disabling the ThemeBuilder app will make the UI appear normal and the Done button will be visible again.
