Opencart 3 does not send messages when ordered

Good afternoon. I need to adjust the website launch and possibly the layout on WordPress. The website displays upon launch as shown in the screenshot. The freelancer who worked on it has disappeared and did not complete the job. We need to check the correctness of the layout and finish it. Both on desktop and mobile versions. The design is in Figma, and the design that needs to be done is also in the screenshots; it seems to be mostly done, but the correct display on different screen sizes is not completed.

There is a page on our website (waiting list) - https://onchainradar.ai It is overloaded and lagging too much. We need to fix this, slightly adjust the animations and some elements on mobile. The site is in HTML and CSS. Please estimate the implementation time and cost. We need this done today or tomorrow at the latest. Thank you.

Assistance is needed in customizing a WIX design template to fit our brand. Preferably specialists with experience working with Wix.

After changing the PHP version from 7.0 to 7.4 on the OpenCart site, two elements have shifted slightly: the menu on the main page and the fields in the checkout process.
