eNewsletter blank screen on create newsletter

I have a problem with e-newsletter on one of the sites in my multisite. On all others it is fine but on the Bristol sub site it hangs with a blank screen on newsletter create. You can only see this problem if you are an admin so I have provided maniu with admin access to this site.

    Hello again @Chris Carrigan, I hope you’re well today!

    I’m afraid that Maniu is away on vacation…

    Can you please set WP_DEBUG to true in your wp-config.php file?

    This should report some errors instead of a blank screen so we’ll be able to figure things out a lot easier!

    Cheers,

    Ari.

    ok. All these are pure informational, the “notices” are there because we have to be compatible with previous versions of wordpress as well.

    This however could be the cause of your issue:

    Cannot modify header information – headers already sent by……………

    Could you please try de-activating ALL other plugins on this site and test again?

    The issue should not exist there once you do…

    You can then start re-activating the plugins one by one and test again to see which one is causing this.

    This is a really common issue… here’s what’s causing it and how to fix it: https://wpmudev.com/forums/topic/wordpress-error-1#post-399933

    Please let me know if that works for you…

    Cheers,

    ok – with the default theme and all other plugins disabled I still get the blank screen and this error message

    Notice: wpdb::escape is deprecated since version 3.6! Use wpdb::prepare() or esc_sql() instead. in /home5/reformgr/public_html/wp-includes/functions.php on line 2876

    Ok – so given it was working on other sites I concluded it must be a database issue. I exported the members then used the plugins own uninstall feature to delete the database then reinstalled it and reimported the members.

    All working fine now – though you might want to flag it to Maniu for reference when he gets back. I took a database dump which I’m happy to let him have.
