Hello @guillaume62,
Thank you for reaching out,
We don’t have a custom template for my account page in OceanWP, so it is the default template from WooCommerce(except for login/register which you can adjust its setting on Customizer > WooCommerce > General > My Account Page).
Note: You can find the login/register classes/HTML in the following path: inc\woocommerce\woocommerce-config.php by searching this class: owp-account-links
To edit the file you must be familiar with PHP and WooCommerce hooks, then you can follow the following article: https://woocommerce.com/document/template-structure/
And made your changes in the child theme on your website. So start with installing the child theme.
Then, by using FTP or cPanel access (if didn’t use the localhost), Go to this directory: wp-content\themes\oceanwp\partials
Find the template that you want to customize and copy that template file.
Then head over to the same path on the child theme. There isn’t an entry folder as a default on your child theme, so you need to create a new one(one time).
Paste that template there.
Then you can edit the template on the new path in the child theme: wp-content\themes\oceanwp-child-theme\partials
* Download child theme: https://docs.oceanwp.org/article/90-sample-child-theme.
* Developer docs: https://docs.oceanwp.org/collection/19-developer-doc.
* It’s working with the /woocommerce/ folder or root of the theme files.
I hope it helps.
Best Regards
