EE3 – Compatibility with PHP8

Hi Tony,

Fully aware that EE3 is no longer fully supported as EE4 is out. We just migrated client site to WPMUDEV hosting to ensure adequate VPS resources to handle site. They were formerly on WP-Engine platform.

We are seeing a couple of PHP8 related issues – and hoping to get some clarifications:

1 – The version of DOMPDF used in EE3 to generate Invoice PDF’s is not PHP8 compatible. Is there a fix or solution?

2 – Paypal Payments Pro gateway in EE3 is failing transactions since migration. Is the Payments Pro gateway library in EE3 compatible with PHP8?

FYI – now that we are migrated to new host, we plan to finalize the upgrade to EE4 in the next 1-2 months however we need existing EE3 to continue to work.
