Hi @Aklapper, the same thing has just happened again, with just 10 photos on Chrome. Could you help, please?

@Aklapper Thanks, I hope I got it ok :-) Just to make sure: the "?debug=true" was used (i.e. reloaded) before selecting the photos and was kept there until the upload was finished:

Hi, @Aklapper, please excuse my ignorance but I am just a humble user and I am not sure what you mean.

Don't know how you did it but I can get to my unpublished translations now. In between, I translated and published another page. Thanks!

@Chronus: After having been instructed by a Czech wiki-colleague, I am pasting the Console "loading" log:

@Chronus I am afraid there doesn't seem to be anything unusual to notice on the browser – see the screenshot. Mind you, I am not an IT person to be sure about that - thanks for understanding :-)
