I want to update a TYPO3 Project from 4.1 to 6.2.9. In order to do that I need to upgrade it to find the most compatible extensions. So I've updated the TYPO3 to 4.5. Now the back end loaded and it shows some arguments that are printed. Also in front end it shows this error.
The requested page didn't have a proper connection to the tree-root!<br /><br />(Broken rootline (failed on page with uid 7))
I fixed this issue.
After going to Install tool. In DB Analyser there are so many tables are not properly indexed. After fixing that this issue has been fixed.
