Error: Undefined class constant 'MAJOR_VERSION'

[markschrik]

Hello,

We did a clean install of WHMCS 8, which on the marketplace is stated as supported.
We have no composer items manually installed, just what came with WHMCS and this package. We followed the readme, did NOT get the source cod, but the release one.

Any clue what we did wrong, or did something change in 8.0 why it does not work? I have no clue.

This is happening whenever we try to open the invoice.
Thank you.

I fixed this for now.

Download the source from github to a temp directory on you linux server: https://github.com/0100Dev/WHMCS-Mollie-Payments
Run in that directory: composer update (vendor files like guzzle are updated)

And then upload mollie as normal to the whmcs modules/gateway map and it should work.

Hi. When I remove the entire mollie gateway, upload it to a temp folder, do the composer update there and then upload the normal files from the source to the gateway folder I get the following;

Whoops\Exception\ErrorException: require_once(): Failed opening required '/home/admin/domains/DOMAIN.TLD/public_html/client/modules/gateways/mollie/vendor/autoload.php' (include_path='.:/usr/local/php73/lib/php') in /home/admin/domains/DOMAIN.TLD/public_html/client/modules/gateways/mollie/mollie.php:3

If I also upload the vendor folder, this one disappears, but I get the old one back that I started with.

Should be fixed in the version 3.0. Please download the latest release from the releases page and try again.

When I upload and replace 3.0 files from the SRC folder, I still get the same errormessages as this topic states.
Is it needed to first remove all and then upload to avoid this error or should an override of files be enough?
I want to remove the whole gateway and upload again but when this does not resolve the problem, what els can I do?
No experience in updating/manipulating a composer update..
