Stripe Recurring Payments: PHP SDK library file

Hello, I have been trying to get help from the www.remarpro.com forum for months on this problem.

I recently fixed a problem of WP Stripe donation button not working. I activated “Enable Debug Logging” and got the message:

WARNING: Stripe PHP library conflict! Another Stripe PHP SDK library is being used. Please disable plugin or theme that provides it as it can cause issues during payment process. (/public_html/wp-content/plugins/recurring-payment-donation-through-stripe/vendor/stripe/stripe-php/lib/Stripe.php)

So I deleted Stripe.php file in my host’s file manager (in the ‘lib’ folder) – which shut down access to my website entirely! The deleted file was not retrievable from the trash folder on file manager – but I managed to get back into WordPress through my host, where I deactivated the Stripe plugin and reactivated it, which gave me access back to my website – AND, the donation button worked thereafter. But it did not regenerate the deleted stripe.php file in file manager.

What I found out after this is that the code for regular long term payments [stripe-checkout-page] must have been deactivated by the reactivation of WP Stripe payments.
When I go into WP plugins and activate “Recurring payment and donation through Stripe”, it gives a similar message:

“Warning: require (public_html/wp-content/plugins/recurring-payment-donation-through-stripe/vendor/stripe/stripe-php/lib/Stripe.php): failed to open stream: No such file or directory in /home2/esoteri9/public_html/wp-content/plugins/recurring-payment-donation-through-stripe/vendor/stripe/stripe-php/init.php on line 4.”

It appears that the “Stripe PHP SDK library” file is the problem. There needs to be an update file of Stripe PHP for this Lib folder? I can see another Stripe.php file in a higher subfolder, but do not know if it is the same file, or risk pasting it back into the lib folder, for fear of crashing my site again.

Thanks for your attention. I am very much an amateur at this, so you help would be appreciated in getting my recurring payments working again.
