I have just updated my company DNN, it was peacefully working since 2007 with version 04.08, now I’ve upgraded it to the 05.02.03 (74) without big troubles, it has been simple doing it on the online server after a test on a local machine.
WARNING! if anyone as lazy as me needs to do this kind of upgrade, be careful, it is necessary first upgrade to version 04.09.05 and then to version 5 to avoid any troubles.
The links to download both versions from Codeplex are accessible from the DNN page even though not very visible, so search them in the Community Upgrade pages.
Said so, everything was fine after the upgrade, except two things: I have multilanguage portals and the language links disappeared. The second problem which at the moment I haven’t yet solved is that the system icons on the menus have malformed urls and are not visible, as soon as I solve the problem I’ll post an addendum to this post.
For the first problem, after some deep breathing, I found the solution on a forum thanks to Mr. Sebastian Leopold from germany, it is simple but a little bit hidden, that’s why even searching all the administrative pages I didn’t found it.
On the Site Admin menu Select Languages, on the Languages page Select a Language different from the Default one in the upper left side combobox.
E.g. Italiano Italia (it-IT); Click on the Edit Language Link below the combobox and on the page appearing check the Enabled checkBox. The Language links or language combobox Will immediately appear on your pages. Repeat for each language you need and for each portal you need to enable.
