C&P Gateway issue since 3.5.1 update

[KMartin]

We recently updated Woocommerce to the latest version (3.5.1). Afterwards, we noticed actions in the dashboard (like saving settings or updating other plugins) led to white screens. More importantly, our login page showed a white screen, which prevents us from logging in. Besides these back-end problems, the site seems to be working fine.

After troubleshooting the theme and deactivating all plugins, we found the problem came from the Woocommerce Click & Pledge Gateway -- we got a white screen right after re-activating the plugin, and the login page displayed the following error:

ERROR: Cookies are blocked due to unexpected output. For help, please see this documentation or try the support forums.

Is there a fix for this issue, or can we expect a Woocommerce Click & Pledge Gateway update soon to correspond to the latest version of Woocommerce?

Thanks.

It seems to be working. Can you tell me what the issue was? I just want to be sure we don't replicate the problem in the future. Thanks.

Good day @KMartin

Our developer said some headers are buffered and not sent the output to the browser which they have resolved. Moving forward there should not be an issue.

Hi. Are you saying that the C&P gateway workes with WC 3.5.1? Your release notes say it's only compatible up to 3.4.5. Thx.

Good day @blatka
