[Geschlossen] Website under heavy load

Background of the issue:
I am trying to translate a page on my website versteckter Link using WPML. I encountered issues during the translation process.

Symptoms:
The website is under heavy load with a message stating 'This website is under heavy load (queue full)'. Additionally, even though the translation is 100% complete and saved, it displays the gear icon, and I need to retry. Sometimes my credits are deducted again. When translating, if it comes across an '>', it shows it as a code marker, making it difficult to set.

Questions:
Why does the website show a heavy load message during translation?
Why does the gear icon appear even after the translation is 100% complete and saved?
Why are my credits deducted again when I retry the translation?
How can I handle the '>' character during translation without it being shown as a code marker?
