I have this issue with e-Newsletter, can't import big list (more than 3,000) and can't export mi list (more than 5,000) and can't send emails...
With the last version of the plugin when trying to send I get to a blank page right away.
Had to go back to previous version of the plugin I had before, and when sending either way by cron or regular I get a 500 error if the list is more than 1,000 subscribers.
Ok you will say its a server issue, but the memory has been increased, and I also moved my database to localhost so I can test and export my users to a csv so I can send them email in other way, and on my localhost if I try to export the subscribers the page stays thinking for more than 1 hour and then opens a page that says page not found.
I have previously sent emails, but that was with very old version of e-newsletter with this latest one I have tried just can't do anything with my lists.
The version Im trying are:
Latest: get a white page when sending emails
version 2.6.1 - get 500 error if a list is bigger that 1000 subscribers.
Thanks for your help.
