I've just gone live with the switch over from vB to XF and for the most part, it's all good.
I do have an issue with one of my top posters who is in Aus (my server is in France).
He does massively long posts. His first attempt failed due to 50k character limit That same post had around 50 images.
I upped the limit to 150k and 200 images and tested it a lot with some Latin filler and it seemed to work.
He says his next attempt gave an error while uploading a picture
and all the previously embedded images after posting now simply said "View attachment =1234"
On subsequent posts he is still getting this this
He says the time to write the post is roughly around an hour. He has no self-logout problems so it's not a session expiring behind the scenes.
This is incredibly frustrating for the users. He is the first to complain about it but being a personal friend, he's also trying to work with me to fix it. I have other users who do similar posts and after spending that amount of time doing a post they simply don't bother after a problem like that. I am desperate for that to not happen.
What can I do from my side to see what the errors are? I have no "server log errors" in acp.
