This screen is shown by default when you don't have configured anything yet. So it's perfectly normal in your situation.

As for the "page not found", I'm puzzled.
Could you send me your log file ? ("ubooquity.log" from the "logs" folder in your working directory)

Like Paul Marvel said, some browsers have a user triggered fullscreen mode that will work with Ubooquity as with any other website.

But I suppose you are thinking of this kind of fullscreen. Harder to achieve. I'll consider it when I work on revamping the online comic reader.
When you click "Set password", Ubooquity should take you to the exact same URL than the one already displayed on your browser address bar (for instance: http://10.0.0.1:2202/admin) and a "webadmin.cred" file should be created in the working directory of Ubooquity.

Could you check if the file is created ? And check if you see anything suspicious (warning or error) in your log file ?
It should obviously not happen. For the moment I have no idea of what might be happening.

Could give me a few details on your setup ?
What kind of device (PC, NAS...) ?
Which OS (Windows, Linux, OS X...) ?
And if you are using Linux, are you using symbolic links for your comics collection ?

If you have a partial log file of the moment the removal starts, it would also help.
And just to be sure, we are talking about the "Launch new scan" link in the "general" section, right ?
Results are in, but they're not good. Bottom line is that I can't fix the problem.

I have tested the two files you sent me (one containing a "Thumbs.db" file, the other containing only images). Ubooquity failed to open both of them on my PC (Windows 7).
I uncompressed and recompressed both of them with Winrar. After that, both were succesfully imported in Ubooquity.

I really don't think that the "thumbs.db" file is the cause of the problem, as the archive opening fails long before Ubooquity tries to list the contained files. The error I get comes directly from the external library I use to read rar files (same problem Emmanuel had).

The problem is that this library is not maintained anymore and I did not find any alternative library (compression libraries are not the most fun or easy things to write). So there is nothing I can do about it, sorry.

Your options: recompress the files that are not preoperly read. Or convert them to cbz (that's what I do as I don't like using RAR files, they are not an open standard so there are much less tools/libraries to work with them).

Ubooquity does not care (in theory) about what kind of files are in the archive. It just keeps the ones it identifies as being images (jpeg, png, gif and, in a future version, webp).

If you can, could send me one or a few files that still can't be opened by Ubooquity after recompression ?
