Cannot export list users - endless Export subscribers

I cannot export subscribers the Export subscribers function just runs and runs, I set up a new phplist v. 3.5.5 and imported my database but still the same problem, any ideas why this should happen, I can’t find anything in the logs

Well got round the problem by setting up a local environment in MAMP and it exported fine so must be something to do with my server set-up

It could be that the page uses Ajax to do the export, and the PHP config on the remote server causes the Ajax PHP script to timeout and silently fail.
ot would be worth testing this, and if it turns out to be correct, to implement better error handling to provide feedback of the error to the user.
