This thread is resolved. Here is a description of the problem and solution.
Problem:
The client is building a bilingual website using WPML, with custom post types created via CPT UI. The specific issue is that accessing posts in English under the /exhibitions slug leads to a 404 error.
Solution:
1) Disable slug translations in WPML>>Settings>>Slug translations, then save the changes. 2) Resave the permalink settings under Settings>>Permalinks. 3) Clear all types of caches. 4) If the issue persists, it might be due to a compatibility conflict with the customized theme. We recommend testing with the default WordPress theme to check if the issue still occurs. 5) Ensure you are using the latest version of WPML String Translation and clear WPML caches from WPML>>Support>>Troubleshooting. 6) Resave the settings under WPML>>Languages>>Language URL format and Settings>>Permalinks again.
If these steps do not resolve the issue or if the solution seems outdated or irrelevant to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If the problem persists, please open a new support ticket at WPML support forum.

Background of the issue:
I am building a new website in French (FR) and English (EN) using WPML, with French as the original language. I created five custom post types (CPTs) using CPT UI. One of these CPTs, named 'Expositions art contemporain', uses the slugs /expositions in FR and /exhibitions in EN. My translations are mostly complete, and the website works as intended in the original language. The issue can be seen at: hidden link.
Symptoms:
When trying to access posts in English under /exhibitions, they all lead to a 404 error.
Questions:
Why do the translated posts under /en/exhibitions lead to a 404 error?
What troubleshooting steps can I take to resolve this issue?
While one of my teammates takes care of your ticket, I will provide you with the first debugging steps.
Have you tried to resave the permalinks in Settings → Permalinks?
If this is still the issue, please check if non-WPML related plugins do not affect this behavior.
Please provide us with a detailed description of your steps to create and translate CPTs. In some cases, screenshots can help clarify any confusion or miscommunication. If you want to share a screenshot, please use the "upload an image" feature below the comment section.
Yes, I have resaved the permalinks in Settings → Permalinks, first thing I did.
I used CTP UI to create my new post types, 5 total. Note that the only one at fault is the one described in my ticket.
After I was done with CPT UI, I went into WPML -> settings ->
Slug translations to activate it. Then, Post Types Translation to set up all my post type slugs at once. Saved, then Settings -> Permalinks just to be on the safe side.
Thank you for the updates. Please try the following steps after a full site backup and check is there any difference in the result.
1) Visit WPML>>Settings>>Slug translations
2) Disable the the slug translation option and save the changes
3) Visit Settings>>Permalinks and resave the settings
4) Clear all types of caches
Please check the attached image. Now the Exhibitions posts archive (the following one) is pointing to Homepage instead of its original page in French. Have you noticed it before.
Did exactly as you described. No changes. Though, I fixed the issue where the translation for the ENG exhibitions archive pointing to the FR home page.

Thank you for the updates. I can log in now. This looks like a compatibility issue. So please allow me to make a duplicator copy of your site using the Duplicator plugin (https://wordpress.org/plugins/duplicator/) for debugging the issue locally.
I had a few rounds of testing in our local copy. It looks like the bug is happening because of a compatibility conflict with your Customized theme. It works fine with the default WordPress theme when all plugins are active. Please check the following screencast for more details.
