Hello,

the translator plugin causes the latest version of Discourse to get stuck on the first loading page.

As soon as the translator is disabled, everything works perfectly. I understand this might not be the perfect place to report this, but I see no other option.

Cheers

Please make sure you’re using the official version of the plugin https://github.com/discourse/discourse-translator. Other people with the same issue were using unofficial forks of the plugin which are no longer maintained.

Hi @david,

you are correct. I was using the LibreTranslate fork.

Thank you very much.

Hello

I noticed that the translations are forced since 2 days ago. Is that normal? Maybe I just need to make a change in the settings?

And when I click on the “translation icon” to hide it, it doesn’t work.

Thank you

This plugin appears to be very beneficial in bridging language barriers.

Quick question, will the plugin also translate blockquotes and preformatted text, such as code snippets, which probably shouldn’t be translated?
