Images(http) and profile in events CPT

have 3 CPTs: working on first one “magic events”.
worked through custom fields, made some inactive (don’t need for events). Havent added any new form fields. Will add some in the other two CPTs.

Problem (see screenshot):
the tabs :photos, special offers and map work fine.
1.Profile tab: shows “date last updated, NOv 30, 2001”
I see that this comes from a plugin I am using which shows the last page last updated (so that for seo purposes… people can see directly when encountering link on web…so I don’t want to remove this plugin). NOTE: it is not a big problem in that the actual entry appears first “magical champers on table mountain”. BUT how do I change that date?? (I suspect that is probably a date that the profile tab was created in geo directory?

2.the “WARNING” at the top of the attached screenshot re image size and http status… the image size is fine (image is 1.8mb, I had set for geo directory at 2mb… then went and changed to 5mb).
I therefore think that this is related to the http… any clues on how to resolve this?

I added the test listing from front end, and am looking at from front end.

Please can I get some help here? I am going to continue on other two CPTs in meantime.

UPDATE: I published as is (per above).
The date last published changed to the today date.
The image appeared in live, with no warnings.

So, my only problem is that this would look incorrect for someone when they try and publish the post themselves, without realising that they can publish and the errors will go away.
