I have a custom post type "Properties". I have around 11,000 entries and each property has around 400 ACF custom fields. When I go to the Dashboard Properties page to edit them.. I get a blank screen. I thought maybe it was cause of the ACF fields, but why do the fields need to load on the listing page?
I detached the custom fields for testing (I did not delete the custom fields from the database) and it still gave me a blank page.
If I reduce the amount of posts in my CPT to just a couple thousand... it works. So what is actually loading when you load the listing page in the dashboard? I assumed it was just the post itself and not the meta data. Is this correct? If it's paginating why would it matter how many posts there are? I assume because there's so many posts with so much postmeta data that it's hitting a memory limit, but even on a dedicated server with 8GB of ram?
I'm not really running a ton of plugins, less than 10 and none are heavy duty besides ACF. Thoughts? This is driving me nuts.
EDIT: I found out on the listing page it's for sure trying to load all the postmeta for what ever reason even though it doesn't display it here. And that's causing it to use too much memory doing this for that many properties. Any way I can prevent that?
