Error after upgrade to Joomla 3.2.1

[deroderuiter]

After an update from Joomla 2.5.17 to Joomla 3.2.1 I tried to install com_phocaguestbook_v3.0.1 But somehow the installation failed. Before the Joomla update I disabled Phoca Guestbook because I didn't want to loose the postings. Probably this is not the correct way to upgrade Phoca Guestbook. Of course I get some errors in the Frond End now (see below). Is there a way to upgrade the Phoca Guestbook without loosing the postings?

Hi, this seems like in your Joomla! 3.2 there is some obsolete code - try to install the component newly - with Phoca Guestbook 3 (to migrate the items, I will write some guide - I hope I will do it before Joomla! 3 will be stable LTS)
