Hi Klaus,
Thanks for reporting this — we’ve investigated it and can confirm that there is indeed an issue affecting the TosRUS autoplay timeout field. The value is submitted in an unexpected structure, which causes the plugin to fall back to the default timeout instead of saving the new one.
This is on our side, not yours. The problem also affects some other grouped lightbox settings, so we’re preparing a fix that will address the broader pattern.
We’re already working on a patch, and it will be included in the next release of Responsive Lightbox & Gallery.
Thanks again for catching this and for your patience while we roll out the update.
