I have an issue with XOT 2.1 stable which only occurs with the machines at school, which unlike my own machines, are running IE10. It does not manifest in unstable. The 'Invalid template_id (could not find in DB)' error occurs whenever you create a new template. Looking at the database, I can see the template records have been created in templatedetails, but the creator_id is blank or null. I have found a workaround which suggests the need for a backport. By copying website_code/php/templates/new_template.php from unstable over the 2.1 version, the problem changes to the known 'invalid session id' problem, which can be resolved by refreshing the page. Can we have an official backport please?
