Welcome to the RetroFE forums
From what I understand it has something to do with the PHP session ID being part of the URL, though how and why is still unclear to me. If anyone has any suggestions: I'm all ears. I'll try to contact hosting support later this week to see if they have any answers.Edit: I've just disabled almost all WordPress plugins to see if that helps any. Let me know if you still have issues, preferably with details that I can show to the helpdesk.Edit: Do you by chance have cookies disabled?
Would a worpdress format suit you ?
