phpList cannot export Subscribers?
In versions 3.0.9 and 3.0.10 of phpList, an issue has arisen where many administrators of phpList mailing list are unable to export a list of scubscribers.
Thanks to Michiel, lead developer of phpList, this has now being solved.
Do you get a compacted iframe like this?
If so, the fix is quite simple, simply replace line 9 of lists/admin/pageaction.php
This has been fixed in version 3.0.11
Further details can be found on the phpList forums along with the affected file if you prefer not to edit phplist core files yourself.
