[TYPO3-english] Upgrade from Typo3 4.3 to 4.3 problem

[Karl Wallace]

Hello again everyone.

This problem I'm pretty sure is related to a custom extension.

Here's the situation.

I have an existing site on typo3 4.2.12, I need to upgrade it to 4.3.x so I 
can provide front end editing for the client.

However, when I upgrade the source files, and then attempt to either remove 
or install ANY extension the front end of the web site breaks and only 
displays this error "NO entry in the $TCA-array for the table "tt_news". 
This means that the function enableFields() is called with an invalid table 
name as argument.".

Now, at this stage I have not compared the database or ran the upgrade 
wizard, if I do this it makes no difference to the error however.
If I uninstall the tt_news extension (version 3.0.1) OR the custom extension 
the site will display ok in the front end again.
I have spent quite a while researching what this could be but have had no 
luck so far. Could the problem be caused by how the custom extension is 
coded?

It was made using the kickstarter so the table definitions and TCA should be 
all ok, unless there's a change from Typo3 4.2 to 4.3 that would affect it.

Thanks for reading.
