New covers not showing!

As the topic says, all of a sudden, when I sideload a new epub, the cover is not shown. Not in "bookshelf", screensaver or on the startpage, but if I open the book, the cover is shown.
To my knowledge, I haven't done anything different than before. You can see what the screensaver looks like on the image enclosed.
Please help!

Edit, I loaded a couple of new epubs on the memorycard in the reader instead, and that worked! How can that be?

The first thing I would try, if you're sure these epubs are properly formed, is a power cycle (not sleep/unsleep, but fully off). Then logging out of your Kobo account on the device, and logging back in again. This will rebuild the database.

The screenshot is no longer there, but I assume the cover was the default cover used by the ereader which has the title and the format in the middle. This is used when for whatever reason a cover can't be extracted or generated. So, it is used for:

- Formats that do not have anything that could be used as a cover. TXT is one of these.
- Sideloaded kepubs that do not have the cover image defined correctly in the OPF.
- A fallback if something goes wrong.

Occasionally I hit the last option. In almost all cases, a restart will display the correct cover. Or opening another book and back to the first. I don't have a pattern, so just ignore it.

My guess is that this was the case for you changing to the SD card fixed it. As covers are not stored for books on the SD card, they will be regenerated when needed, so that will mean the cover is more likely to be correct.

I did a restart that didn't help. But if I log out of the account, won't my collections be erased? I did that about a year ago and had to start from scratch with all my collections.

That's what I thought it was.

Yes, if you log out and back in, it will reset everything and reprocess the books.

I you use calibre, you can try my Kobo Utilities to delete the stored covers for the book. Then restart the device to clear the memory cache. That should get the cover regenerated when it is needed.

If that doesn't fix it, I don't know. The device generates epub covers from the first page of the book. If that displays OK on the device, the cover image should generate. I could see a problem if the space in the main memory was running out, but I think there would be worse problems if that was the case. The other possibility is a problem writing to the card. But, again, I would expect more problems if the card was failing.

I strongly and vigorously recommend using Calibre to manage your collections. I guess I kinda assumed you were already. Sorry bout that. Not only is it quicker and easier, but it makes it trivial to recreate your collections should your device need a factory reset, or be stolen, or break.

I have all my books in calibre, but I haven't gotten around to learn how to make collections there yet. So I'm doing them manually in the Kobo.

In Calibre, go into Preferences, Plugins, Device Interface Plugins, and scroll down to the Kobo plugin and double click it to open up the options.

You'll see an option to "Create Bookshelves", check it. In the box next to it enter:
series, tags

Whenever you send books to your Kobo readers, they'll automatically be put into collections based on the series names and tags that you have entered in Calibre.

It couldn't be simpler to do.

Or, if you prefer to create your own shelves and leave Tags as it is, read the sticky in the Kobo forum about shelf management.
