When I want to go to the next slide, every other slide an error message pops up. I tried searching for the error on Google, but couldn’t find anything useful. I am using the German version.
The error message says:
“Ein Fehler ist aufgetreten.”
Is there anything I can do to solve this problem?
Could you try to describe the error in more detail? Is there an option that says “Copy Debug Info” or equivalent? Could you try to explain what you are doing before the error pops up and what happens once the error pops up?
A recording would probably be better.
Yes, there is an option, that says “copy debug information”.
I can open the app normally, even the samples work at times. But after a couple of slides the error message pops up and I can`t continue.
Does that help?
Could you click on that and then paste it in code blocks (like so ```your code```)?
Also, please do send a recording like @sorata suggested.

anki.errors.InvalidInput: missing template```Sorry, don`t really know, how to do and send a recording 
Try running Tools > Check Database and post what it shows
I can’t find “tools” and “check database” either
Open the Anki app, move your mouse to the top and then you should be able to see a bar which has some buttons on it with names like “File”, “Edit” and so on.
In accordance with the “teach people to fish” principle, I’ll let you know that a search in https://docs.ankiweb.net will give you almost everything you want to know about a particular option.
For example, searching “check database” gives me this:
. . . try the Tools → Check Database menu item to make sure your collection doesn’t have any problems.
I think , I got it.
That’s what it says, when I go to "check database:
" 1551 Karten ohne Vorlage wurden gelöscht.
Datenbank neu generiert und optimiert."
I´m not sure, if that’s what you meant
For other contributors: The error states “1551 cards without template have been deleted. Database rebuilt and optimized”.
Anyways, you were missing a template. This shouldn’t normally happen. Did you want to keep the cards or are you okay with them being deleted? If you want to keep them, you should restore from a backup file now.
Thank you!
