Cannot Set Featured Image After Installing NextGen (5 posts)

    Posted 3 years ago #

    Cannot set my featured image in a post or change it after installed 1.9.6 nextGen gallery. When I go to add or change it, it hangs on SAVING, but it never saves it.

    This is a MAJOR problem. I even deactivated the plugin and still have the same problem.

    Need help on this asap please.

    Thank you

    I've got the same issue. This is what I've tried so far:

    1) Since I upgraded NextGEN through WordPress I thought I'd try upgrading from scratch. I deactivated the plugin, deleted the folder from the server, uploaded the new files and re-activated it again. Made no difference.

    2) Tried saving the featured image in Firefox, IE and Chrome, I have the same problem in all 3.

    3) I've deactivated other plugins then re-tested the save featured image link but am still having the same issue.

    I can't think what else to try.

    I managed to fix it!

    I did a general search on Google about not being able to save images and came across the below thread:


    A member there suggested to use Google Chrome and load the half-page editor (by pressing Ctrl+Shift+J) and see if any errors appear when trying to save the image. This is what I got:

    POST http://www.mysite.com/wp-admin/admin-ajax.php 500 (Internal
    Server Error)

    I then looked up that error on Google and found a few users talk about updating the server mod security/cpanel settings. So I emailed my host and this is what they said:

    "Most likely this is a mod_security issue, yes. graqpping for the IP you opened this ticket from in the Apache error log reveals:

    *Error message*

    I've whitelisted against this URI and rule-id. Please attempt again and let me know if the issue is resolved or persists."

    This fixed the issue, I can now finally set featured images again!

    Hope that helps.

    Quite frankly, this surprises me. The issue that NextGen cannot display the featured images in a post has been around for nearly 2 years...

    Google search results on this topic...

    Basically it shows up when you click "use as featured image" when creating a post. However on the front-end, the picture will never show.

    I am working on a local machine without any security plugins and it's still not working (as in the last 2 years)... Really a pity, such a great plugin and it would be such a great replacement for the built-in media library, if only it could be used to attach pictures to articles in featured thumbnails...
