John

Got it. I will try to find the right way to do this. Again, thanks for your help.

If this helps, for example, when I generate 4, I can watch them be created, but the thumbnail of the thumbnail image is broken. Right click/link is https://www.squeezehorns.com/media/thumb_tmp/20230929twotone2_thumb1.jpg?2126224182

My WP knows where my Media folder is and works fine otherwise. I don’t use a plugin for that.
I slightly modified (for posting) the test command in/output, replacing my actual server user name with ‘user’ and my site with ‘mysite.com’ (user/mysite.com). The test seems to complete, but I can’t find the output file anywhere. Feels a little ‘permissiony’ which isn’t my forte.

Thanks!

Thanks! That sounds like my solution. Much appreciated. And good to know too that 90MB is low. You’d think that as computing power, including memory, gets cheaper over time, they’d up their memory limits (keep customers happy) but at the same time they’ve developed Managed WordPress products (which are a lot more expensive) so one has to conclude that there’s a squeeze play going on to motivate ‘upgrading’.

I guess I didn’t realize that Registered Users automatically become Registered Subscribers as soon as Subscribe2 is activated.
It turned out that the reason post notifications weren’t going out was simply that I hadn’t noticed that the default for Appearance > ‘Disable email notifications is checked by default on authoring pages?’ Is checked. And because there was other plugin info taking up real estate on the authoring page I hadn’t even seen the Subscribe2 check box beneath the Edit window. One thing that might help others, if you can confirm it… Our friendly tech support at LightningBase told me that as long as I was getting emails sent through Subscribe2 > Send Email, that would imply that the server was sending okay.
P.S. Creating a ‘Test’ category and bulk unsubscribing everyone else from that category helped me do a lot of testing without bugging anyone. Thanks mattyrob!

I received a response directly from the developer.
