I downloaded and installed JF WELL BENESSERE template, but before using it I was trying to update Joomla 3.0.0 to the latest version 3.3.6. but it does not work. The installation was ok and the template with all quickstart items shows.
We tried to update first to 3.2.7 as well as directly to 3.3.6 through installer and through FTP but it doesn't work. We get the message (when entering to Joomla Administration main page):

An error has occurred.
1146 Table '...ourtable..._postinstall_messages' doesn't exist SQL=SHOW FULL COLUMNS FROM `r2gfn_postinstall_messages`

Do you have any ideas why it won't work?
We installed everything through QuickStart installation.

Thank you so much in advance!

Try to go to Extensions->Extension Manager. Click on Database and click on Fix at the top.

Thanks for the reply, but when I click on the Database, it goes back to the error - I'm sending a screenshot now.
So, I can click on Extension Manager, but not on the Database.

1- Import sql (attachment)
2- Update to Joomla! 3.3.6
3- Go to Extensions->Extension Manager. Click on Database and click on Fix at the top.

Now you have the latest Joomla! version, 3.3.6.

Thank you!

Hi and thanks for all the effort once again, but the problem is still there, now with different error.
We did as you instructed, and also in 3 ways:

1. we followed the steps you wrote as continuation to our previous (unsucessfull) update where we overwrote the update to 3.3.6. after sql import once again.

2. we uninstalled everything, and started from the start and then followed your instruction (meaning updating to 3.3.6 only after the sql import) using Joomla stable update package

3. following the steps and updating to 3.3.6. with the full package Installation (not just update package)

The Database Fix worked every time.
At the end of every above mentioned situation we got this error on admin Home Page (screenshot):

Thanks in advance.
