I am trying to: our website (both betasite.naseej.com & naseej.com) keeps breaking after the last WPML update, giving us error 503 on front-end, when we disable WPML from WordPress backend, the website comes back online. Link to a page where the issue can be seen: hidden link
Symptoms:

Questions:
Why does the website break with error 503 after the WPML update?
How can I resolve the error 503 issue caused by WPML?
