Hej pel.
Opgrader til 5.6 og husk en ordentlig back-up først, for det tilfældes skyld at det mislykkes, så du skal til at reinstallere.
Derefter læser du (grundigt) alle indlæg i min og RiCo's tråd om webmail og Danish Language support på Dan's forum (jeg har set, du har været der), og kør opgraderingen efter Dans anvisninger - så er du på.
Hos mig spiller webmail nogenlunde stabilt med 8 brugere (venner og familie i Europa).
Gree.....
Sorry - my apologies to all 'non-danes' !
Upgrade to 5.6 and remember a current back-up in case something goes wrong so you have to make a fresh 5.6-install.
Then read all the submissions in the thread on Dan Browns forum, concerning Danish Language support in Horde ( I saw your 'fingerprint' there).
Do the upgrades as stated by Dan, and you are up and running.
On my server it's performing smoothly and is fairly stable with eight users (friends and family throughout Europe).
Greetings
WyRon
