I used the default "Contact Me" form which was already created.
I translated it in FR using the Translation Management.
I added the form on a test page (pasting the shortcode) : hidden link
Created a duplicate version in FR : hidden link
I submitted the form on both the EN and FR version of the page.
Here are the results :
- The form is correctly translated (fields / button)
- Success message is displayed in FR in both cases after submission
- Both email actions that are set up on the form, are sent translated in FR
I didn't receive the emails but we can check in the logs : hidden link
So yeah there are issues even on this sandbox environment.
Success message and email actions are always translated in FR, even when submitting on the EN page.
FYI I installed Classic Editor to make the page, as I'm always using it instead of Gutenberg.
I also did a test by disabling it, just to be sure... same result.
Thank you very much for reproducing the issue on the sandbox site.
After trying a few times, I was able to reproduce the issue, but it doesn't happen all the time. For this reason, I have escalated this ticket to our 2nd tier of support, where our specialists will take a deeper look into this issue.
I will get back to you as soon as I have more information.
No news yet. I was able to reproduce the issue intermittently on the sandbox site, and our 2nd-tier specialists are trying to reproduce it so they can investigate the cause of the behavior.
