[SOLVED] 500 on some albums after migrating from subdomain to main domain

Hi everyone, 

For context, I recently moved the website installation which was 100% working on a subdomain, to my main domain. That involved moving all the website contents from one folder to another. 

I noticed today that I get 500 on some specific albums, not all. Is there a way that can help me debug what might be wrong? 

Working examples: Not working example: There are more pages suffering from 500, but just leaving some examples here.

The reason for this is missing MBSTRING extension on your server, see your diagnostics:

I can easily see this, because when viewing the source of the broken pages, you can see the HTML is cut off half way as soon as it encounters the issue. Why some pages work, I'm not sure, but either they were already cached before migrating, or they have different characters or modules on the page that requires mbstring.
