Hi,
This is similar to https://www.ads-software.com/support/topic/undefined-class-constant-belfius/. You probably have another plugin using our API client which is not up-to-date. Disable the other Mollie(-related) plugin.

Let me know if this fixes your problem.

Problem on several other websites. Downgraded them all to 2.3.1

@lvangunst, no I don’t have any other related Mollie plugins running.
This issue is purely from Mollie plugin only.

I have just tested on a new clean staging environment with only WooCommerce and Mollie 2.4.0 and it happens too.

I see other people have same issues too.
I have stopped upgrading websites until this bug is resolved.

Please check again from your side.
THe error states very clearly that the error is coming from “Class ‘Mollie_WC_Gateway_Kbc’ not found ”
This has nothing to do with other (related) plugins.

I have the same problem. I don’t have other plugins that use the Mollie API. Most of the WC settings are unavailable after upgrade. Blank screens. Other screens work partially. After restoring backup of the 2.1.3 version all works fine again.

@argosmedia, where did you download the previous version?
I’m looking for that one too until this bug is resolved in 2.4.0

Thanks!

there you go: https://we.tl/pAJZH5wKTO

I restored the plugin directory from a backup from yesterday. I can zip and send it if you want. Email me at info AT argosmedia DOT nl

Freshmedia beat me to it ??

I would like to mention that the same has occured to my site, same error message too. Disabling the plugin stops the errors from occuring. Given that the error is with KBC, which was added in this update, I would think some bug was introduced in this update.

@freshmedia: thanks man!

Same problem here!

??

@mschouten, un-install v 2.4.0 and install v 2.3.1 back until this bug is resolved.

Same problem here. WC settings gives blank screen, checkout-page for customers also. Will have to roll back.
