Forum OpenACS Q&A: Re: Problem with weblogger since 5.1 upgrade
Is this the weblogger-portlet? Because that did have this bug, which I have just fixed on oacs-5-1 branch.
lars-blogger itself shouldn't have.
What's happened is that entry_date and posted_date has been replaced with a single entry_date, which is much more sane. All references to posted_date should've been replaced with entry_date already.
