Hello,
I'm actually using OC v2.2.0.0. and running PHP7.4.
I recently installed this Square payment gateway extension by iSense and found a big problem: Customer placed an order, but got charged same amount for 2 time on customer's credit card. My Square account got suspended because of this double charges issue.
Please help urgently. Thanks in advance!
There is probably a link to their support on the extension
You can use their website https://isenselabs.com/users/login
or you can click the SUPPORT button on the opencart marketplace
For anything more urgent you can request commercial support viewforum.php?f=88
Are looking for someone who is online now to provide paid support? I am not available but I am sure if you are asking for that there are three or four good developers that are around at this time.
It would be helpful to provide your theme, extensions - especially cart payment related and a link to your site.

I opened a support ticket 4 days ago at developer's site https://isenselabs.com/users/login, but no response so far.
