[exhentai][warning] Enabled Multi-Page Viewer is not supported

That's the problem. You need to disable the mpv feature if you want to download with gallery-dl.

[thomaslty]

disable the mpv feature

how can I disable that?

[mikf]

There's an option field near the bottom of your exh settings:

On another note: I do not get this particular error for this gallery. For me it fails as expected:

$ gallery-dl https://exhentai.org/g/1861972/7770ca480e/
[exhentai][warning] Enabled Multi-Page Viewer is not supported
[exhentai][error] Failed to extract initial image token
[exhentai][info] No results for https://exhentai.org/g/1861972/7770ca480e/

Do you have any other "special" options enabled that might cause this?

[thomaslty]

I already disabled in the setting as you shown, but it still output the mpv warning.
Regarding your failure to download the gallery, it happens on my side too, but it can be opened from browser, strange. Could you please try this url https://exhentai.org/g/1831956/466b17a5ce/ , this time it produce "IndexError: string index out of range" propertly

[mikf]

Could you please try this url https://exhentai.org/g/1831956/466b17a5ce/ ,

# with mpv enabled

I should really just add support for downloading with MPV enabled, but anyway: Could you run this URL with --write-pages and upload the generated 01_https_exhentai.org_g_1831956_466b17a5ce_.dump file so that I can see what is different on your end?
