Error: Not a valid URL

Hello @voodoochill,

Is your website currently using any other Stripe-related plugins? This error often occurs when another plugin is using the same Stripe PHP library WP Simple Pay uses, but are using an older version.

WP Simple Pay uses the latest version of the Stripe PHP library and the latest version of the Stripe API.

Hi Spencer, thanks for speedy response.

I am also using Woocommerce Stripe gateway but I get the issue even if I deactivate that.

Thank you for the information @voodoochill,

Are you able to post the contents of Simple Pay Lite > System Report? Please redact your “Home URL” and “Site URL” if you do not want them visible.

Also, in your Stripe Dashboard, do you see any requests similar to POST /v1/checkout/sessions when you visit: https://dashboard.stripe.com/test/logs?method%5B%5D=post&method%5B%5D=delete&direction%5B%5D=connect_in&direction%5B%5D=self

Thank you @voodoochill. Is that Stripe account the same one you are using WooCommerce with? I would expect to see more logs from this year.

Do you have Webhooks configured in https://dashboard.stripe.com/webhooks for WooCommerce? Can you verify those URLs are valid?

No it’s a different stripe account.

In the stripe account I have for Woocommerce I have webhook: https://tamingthesaxophone.com/?wc-api=wc_stripe

I’m not sure how to verify it’s valid, but it’s what I pasted in from the Stripe settings in Woocommerce

@voodoochill Are you able to try connecting WP Simple Pay to the same Stripe account that you are processing WooCommerce payments with temporarily? Does that allow Stripe Checkout to function?

Done that, same thing happens

Thank you for testing @voodoochill. Can you please verify the settings in “Simple Pay Lite > Settings > General” for “Payment Success Page”, “Payment Failure Page”, and “Payment Cancelled Page” point to valid pages? Please resave those settings once verified.

I was able to reproduce your error by assigning a page to “Payment Success Page” then deleting that page in WordPress. Ensuring each setting has a valid value should solve your issue.

• This reply was modified 4 years, 10 months ago by Spencer Finnell.

Yes they point to pages, but they are random pages of my site nothing to do with payments.

But there are only “Payment Success Page”, “Payment Failure Page”,

Not “Payment Failure Page”

I should point out the plugin was installed then uninstalled then reinstalled . Are those special pages that are created on installing? But not on reinstalling? Could that be the issue?

• This reply was modified 4 years, 10 months ago by Mr Lucky.

Sorry, “Payment Cancelled Page” is being added in an upcoming release.

When WP Simple Pay is activated pages are created and assigned to those settings, but only if they do not exist previously. Were your pages perhaps moved to the Trash?

It doesn’t matter if you choose pages that WP Simple Pay created, they just need to be assigned to a published WordPress page. Ensure the page you have selected for “Payment Success Page” has the shortcode “[simpay_payment_receipt]” to output the payment receipt.

I deactivated the plugin awhile back (and deleted it)

Then recently I thought I’d try it again so installed it.

The success and failure pages I mentioned do refer to existing pages, but there is no shortcode, they are just pages that I have had for a while and nothing to do with this plugin

@voodoochill Please try the following:

1. Visit “Pages > Add New”
2. Add “Payment Confirmation” to the title and “[simpay_payment_receipt]” as a Shortcode to the page content.
3. Visit “Pages > Add New”
4. Add “Payment Failure” to the title, and anything you want to the page content.
5. Visit “Simple Pay Lite > Settings > General”
6. Assign the pages you just created to the two settings.
7. Click “Save” at the bottom of the page.

Does that resolve your issue?

Yes of course!

I must have deleted those pages when deactivating and uninstalling, but when I reinstalled, the pages don’t get created.

But I was also wondering, does this plugin create any database tables?

@voodoochill Great!

WP Simple Pay Lite does not utilize any custom database tables. WP Simple Pay Pro creates a custom database table to manage Webhooks received from Stripe.
