Hi, I wonder if anyone can help. After rebuilding my gallery I now have missing image sizes, resulting in lots of error images instead of the actual images. I know the images are there, as when you click thru into the galleries, you eventually see them.

When I say rebuild... For reason I don't want to bore you all with I had to go back to a manual backup I made of all the Piwigo files on my server. After I'd done that I put back in place the existing config and upload files.

All seemed to work well, except as I say, now various image sizes are missing.

I'm thinking I need to somehow force Piwigo to rebuild all the various image sizes, but I can seem to work out how to do it.

Or maybe there is something else I should do?

Any help/advice welcome.

Thanks.
