I've just updated from 1.4.5 to 1.5.0 with the "Download the upgrade package only" zip. The notice list - most of which were my own old 'forum has been updated' announcements - is empty. Then I try and create a new notice, I get "Please enter a valid value." message. When I try and submit the blank form on its own, I get: Please correct the following errors: Please enter a valid value. Title: Please enter a valid title. Message: Please enter a valid message. ...so no hints as to what's blank there. File Heath Check shows some files in the install directory were "File does not contain expected contents", re-uploading the folder from the full install zip does not fix the messages. Any ideas?
