Stripe Payment

I use WCFM for my marketplace, even though Stripe Split Pay is not working with WCFM. Every time a seller tries to connect to Stripe Payment an error message occurs:

{“error”:{“message”:”Cannot onboard via express oauth due to gated access.”,”code”:”forbidden”}}

I read about this issue here and found a code snippet to use in my functions.php.

add_filter( ‘wcfm_is_allow_stripe_express_api’, ‘__return_false’ );

I pasted this code, but now another problem occurs when a seller tries to connect to Stripe Payment:

{“error”:{“message”:”Standard OAuth is disabled for this account.”}}

I re-checked & re-entered my Stripe Client ID and Live+Secret Key. Everything looks good. Even OAuth for Standard Accounts option is ON

Regarding the redirect URLs, I tried to add them to my Stripe Connect URIs but one of them (https://DOMAIN.com/store-manager/settings/) not working. Stripe gives me “Invalid URI” error.

The other redirect URL (https://DOMAIN.com?store-setup=yes&step=payment) is working fine, at least stripe accepted it when i entered as a new URI.
