I wanted to submit my app for the App Store on iTunes Connect, but whatever I do I got this last message telling me there are still one or more errors on the page. Unlike earlier errors this error does not focus on a particular place on page, nor are there any red-colored fields.
Things I did:
- filled app info
- filled contact info
- uploaded screenshots for all supported sizes
- uploaded binary / selected on itunes connect
- filled rating form.
Here is the screenshot:

If there are no errors and it just say, "There are one or more errors on page
"
following can be solution.
Click on "Pricing" tab
and choose Price Tier
as Free
or your price
and go to your app again and Submit, Cheers.
Adding onto this list so other people troubleshooting have something to try. For me, I had my Secondary category set to "Magazines & Newspapers" and setting it back to default "Secondary (optional)" let the app through to review with no problems.
I was having the same issue i.e there are one or more errors on the page... and no indication what error is there. Finally I resolved it by traversing each option above. Though all i set was "Pricing" and as my app was free so i checked that option. Then i came back to the first tab and hit submit, and it worked, with no error.
You should inspect the response from the apple server. The response contains a JSON. Search for "errorKeys", where it is not null or []. This way, you can find out the exact problem.
In my case it was saying "You must choose a version release option.", basically I needed to checkoff the pre-order option to expose the UI to select "Manually Release" option. After I selected that option, I checked back the pre-order option. This resolved the problem.
Had the same issue and for me the solution was to go into the media manager and tick all the "Same as 5.5" screenshot check boxes. I only uploaded 5.5" screenshots. No IPad but I assume if you support iPad the same applies there.
I fix the issue by adding a cover art. scroll down at the screenshot page and upload the cover art.

For me there were 2 languages got selected and removed a one while keeping the default.

For me there was a tiny red Edit button for Rating in the bottom of the version tab. If you didnt answer questions to get the rating, you need to scroll down and fill that out.
it happened with me also what worked with me was increasing the the date of preorder availability
Well, even after selecting price the error didn't go away, at the end I witnessed it was because I selected Magazines and Newspapers as a category in the App information tab, which might require some additional information. After changing it back to some other category the error goes away and I submitted Application successfully
My case was different when trying to submit a Newsstand app with an in-app purchase. Under the versions tab, I had to go to the in-app purchases section (NOT the in-app purchases tab) and add the free subscription I had configured to my build submission.
I had uploaded a new app v1.0 which got rejected. I updated the version to 1.0.1 in the plist and selected the correct version on App Store Connect. The problem I had was that my original app version was manually still listed as 1.0.
Changing that to 1.0.1 solved my problem.
In my case the last screenshots tab was not visible because of browser scale

So when I make zoom smaller it becomes visible

For me this thread helped: https://forums.developer.apple.com/thread/115663
The answer:
I faced the same issue few days ago on my new App, in my case, after investigation Apple Team found out that I choosed “Magazines & Newspaper” category for the app, or if I am using the Newsstand plist key. If so, then the app must include an auto-renewable subscription.
Then after I unselect the secondary category in App Information Tab, I managed to submit for review without error.
