Visual Editor and translations not working after update

Hi!

So a while back I was working on my recipe blog and usually WordPress and all my plugins get their updates automatically. On this day, though, there was a bar on the top of the page that I should update TranslatePress. I was hesitant at first (you know, updates can always cause problems), but went through with it and it looked like it went through without any issues. Unfortunately, I then discovered that nothing was working properly anymore.

The first thing that concerned me, was that the visual editor hasn’t worked properly anymore. When I started the translation mode and wanted to click on a string or text to translate, there was no pen-icon to click. Sometimes if I get in and out of the translation mode, it will come up and I can click on it. It then also shows me the forms to enter the translation. But whenever I try to save it, it looks like it does but on the website it never shows.
And there used to be a list of all the texts to translate, that I could choose from and enter translations for – the list is empty now, only the bold-written category headlines visible.

Then I looked around here to find help and read that you can also translate your webside by working in the database and entering the translations directly into the table. I tried WP Data Access and found the dictionary database. I entered some translation that I knew where to find on my website. I saved those translations but they never showed on my webside. Then even tried another plugin (phpMyAdmin) for the same purpose – no success either.

I’m lost and I want to release my recipe blog soon. Please, can anybody tell me how to get it working again? (Unfortunately I don’t know how to upload any screenshots, my website is still in “coming soon” mode and only admins can see it right now …)
