This thread is resolved. Here is a description of the problem and solution.
Problem: The client is experiencing a repetitive internal server error (error 500) that occurs frequently. Disabling the WPML plugin or resubmitting the permalink of the homepage temporarily resolves the issue, but it persists and affects the website's functionality. Solution: We have identified that the Object Cache is causing the issue. To resolve this, follow these steps: 1. Navigate to the WordPress Dashboard. 2. Go to Settings > Object Cache. 3. Click the disable button for the Object Cache. After performing these steps, the pages should work without issues, even with all WPML plugins active.
If this solution does not seem relevant to your situation, please open a new support ticket with us.

I am experiencing a repetitive internal error (server error 500) that occurs frequently. It is quite persistent, and I am not fully sure why it is happening.
The resolution is simple: I disable the WPML plugin - everything back to normal and the website is reachable!
Another resolution way: go to the main homepage and commit its permalink.
The underlying root cause is unknown, and it is a persistent issue that I can no longer ignore, as it will happen again soon. My website provides an online service with paying customers, and this issue is causing me to lose existing as well as new visitors.
As I said before, resubmiting the relevant post/page will resolve this issue but it occurse frequently for any other page/post. It is frastrating and the customers complains. Don't know what to do.
Thank you and sorry for the late reply due to holiday season. Would you please provide the staging/copy version of your website so we can do more investigation on it without the fear of effecting a live website?
Please set the next reply as private and provide the staging website information so we can continue.
Thank you for the site access and thank you for all the steps you took so far.
Rest assured that we do our best to be able to find the reason behind the issue.
I found out that the issue is the Object Cache. As soon as I went to WordPress Dashboard > Settings > Object Cache and clicked the disable button for the object cache the pages in question worked with no issues even when all WPML plugins were active.
