PHP error when using stripe

[dietrichmd]

When attempting to save stripe info in settings the site gives a generic Wordpress error, yet the data saves. On the front end, the user can get all the way to the payment page and when they click pay with stripe, the site gives the generic error.

Upon searching the logs, I see the following:

Any ideas @liedekef ?

This is because another plugin (or even the theme) also includes (a version of) the stripe library. EME only includes its included version of the stripe library when needed, where the other plugin seems to include their version of the library in/on all pages.

Now, a possible fix (untested), could be to replace in the file eme-payments.php the line
require_once 'payment_gateways/stripe/init.php';
with

if  (!class_exists('\Stripe\Stripe')) 
   require_once 'payment_gateways/stripe/init.php';

Now the problem is that then I don't have control over the version being used ...
But first try it (should work), the replacement should be done 5 times in eme-payments.php.

Well, that didn't fix it, but not because there was a problem with the code, but because the client had the API keys in backwards. Go figure. Thanks @liedekef

So, does this mean the code helped to resolve the first problem and then there was another due to wrong settings?
Because I can include the mentioned code by default in the next version then.
