@Amire80: Yes, I haven't deleted these translations yet. I hope the access to them could be somehow restored. If not - I will have to delete them and start new ones. I will provide the names of the articles and links to the translation itself:

• Ascraeus Mons → Гора Аскрійська (link)
• Mr Selfridge → Містер Селфрідж (link) (I deleted this from translations)

Another user (@Ata) tried to take over the second one to finish the translation but says she couldn't for some reason.

@Piramidion Can you confirm that this still happen when you try to open that draft at https://uk.wikipedia.org/wiki/Special:CX when logged in as user Piramidion? How about the two newer drafts you have?

The data is in the database, and I did not find anything suspicious about it. I am sure it can be restored.

@Nikerabbit Yes, it still doesn't load the translated text and throws me out to the "all translations" page. As for the other two translations, the small one I started just to play with and see if the issue occurs once more. But it didn't, no matter what my actions were. It could also be somehow connected with some "bigger" articles, but I don't know for sure.

As for the third one that I'm currently translating - I do it rather carefully and to leave that translation I press ctrl+s first, so it works fine so far.

Today I did the next:

• I entered my translation,
• quickly clicked to add a paragraph for translation (just to see what happens)
• and got the warning saying that I've got unsaved translation and asking whether I really want to quit without saving them.
• I've pressed the "leave this page" button.

I did nothing else, except the above. By the way, this was the first time I saw this warning. And the blue bar beneath the translation image (on the "all translations" page) has changed somehow. I think I've changed the translation in someway, but still cannot enter and see what it looks like.

This is quite curious. Could you perhaps add a screenshot of the change you mention? It will help us identify the problem more easily. And if you see any JS errors we'd really appreciate if you add them too. Thanks.

This is the error I get:

Don't know if I did everything right (I didn't use the console earlier). And there are many warnings of deprecated parameters like

Use of "wgAction" is deprecated. Use mw.config instead.

And today another problem occured: the other my translations seem to be deleted: they didn't load text (but didn't throw me out) and the blue status bar now is empty (it is grey). There was some error, but I didn't save it. I started another translation to see what happens and I can see that the tool saves the page while no changes are made (I entered my new "test" translation and wanted to go back but chrome didn't let me since "save" was in progress). I think it could somehow save my earlier translation as empty before it was loaded but I'm not sure.

As for the first case, the screenshot is irrelevant, the blue bar earlier showed ~70% done, now it shows 40%, all of which is "from machine translation".

Similar issue? - https://www.mediawiki.org/wiki/Topic:Sf76hppcfcaa8sz8

Yes, similar issue concerning the deleted translation. This issue seems fixed : I've translated a new text, and it is still available (but not my old one).

I have looked at the database again and the only interesting thing I found about "Ascraeus Mons" was that it has been updated at 20150409-181601. @Piramidion Do you remember accessing or trying to access that translation on Thursday last week?

I also checked our access logs for the HTTP 503 but did not find anything obviously related to ContentTranslation.

@Nikerabbit: This comment I did post on Thursday last week. Now the blue status bar shows only 40% translation done all of which is "from the machine translation", while earlier I had over 70% finished. And in the console I still get this 503 error.

What do you see if you try to open https://uk.wikipedia.org/w/api.php?action=query&format=jsonfm&list=contenttranslation&translationid=34778 in your browser?

I get Wikimedia Error.

I think I was able to reproduce.

1. Pick a long page from https://en.wikipedia.org/w/index.php?title=Special:LongPages (I avoided lists because tables are problematic)
2. Select it for translation, e.g. https://uk.wikipedia.org/w/index.php?title=Special:ContentTranslation&page=Greek+government-debt+crisis&from=en&to=uk&targettitle=Greek_government-debt_crisis , and wait for the page to load
3. Click some paragraphs to have the machine translation added (which is still in English here because there is no en-uk pair)
4. Get the ID at https://uk.wikipedia.org/w/api.php?action=query&format=jsonfm&list=contenttranslation and enter it, e.g https://uk.wikipedia.org/w/api.php?action=query&format=jsonfm&list=contenttranslation&translationid=35887

Observed: the request takes a while and eventually I get a Wikimedia error:

Change 204224 had a related patch set uploaded (by Nikerabbit):
Optimize draft content loading query

https://gerrit.wikimedia.org/r/204224

Thanks to @ori who connected this to the error Fatal Error: request has exceeded memory limit I was able to figure out that we had one very very inefficient sql query. P522 has some more details.

Change 204224 merged by jenkins-bot:
Optimize draft content loading query

https://gerrit.wikimedia.org/r/204224

@Piramidion The above fix is now deployed. You should be able to access your draft now.

Yes, now it doesn't throw me out, though I've lost my translation (there's only one paragraph saved which I added on Thursday). Thank you for fixing this! At least I won't be afraid of losing my translations again.

What is "go page"? Can you try accessing your draft through your dashboard? translationid is required in the url to access saved drafts.

The issue of backspace going to another page might be issue of T94567, or then it might be that all the current content was saved in the draft database.

https://sv.wikipedia.org/wiki/Special:Inneh%C3%A5lls%C3%B6vers%C3%A4ttning > https://sv.wikipedia.org/w/index.php?title=Special:Inneh%C3%A5lls%C3%B6vers%C3%A4ttning&page=Suicide+Squad+%28film%29&from=en&to=sv&targettitle=Suicide+Squad+%28film%29&draft=35808 = No progress except for a false progress bar. :/

Drafts are private so I can't see what you see. Can you check that there are no JavaScript errors or other failures in the developer console? I also checked and the source article has changed today which might affect our algorithms ability to re-match things: that would be a separate bug.

I copied the plain text content (excluding references) of the draft at P527. Can you say whether it contains everything you had translated or is it missing sections?
