I'm just going to pile some stuff in here as a record, because there is something fundamentally wrong with the installation, and there's no way I can figure out where to start working on it.

My Piwigo setup seems dead, and nothing I can think of has revived it.
I'll post this stuff then get on with looking for some other photo hosting software.

It could be the version of Piwigo that Asustor uses in its ADM.
Or that the ADM isn't friendly with Piwigo anymore.
On the other hand, could be that v12 is just incompatible with Asustor.
Whichever way round it is.

It could be corrupt bits of previous installations. I've reinstalled Piwigo twice, once leaving it with the generic settings, and once with various plugins, themes, and altered config settings. Makes no difference. It's not a bug in a theme or plugin that's brought the whole thing down.

Perhaps I've not removed enough traces of the previous installations. I would think that removing the ADM app, and dropping the MariaDB would be enough. Done that twice now. Created a database, installed piwigo, saw problems, uninstalled the app, dropped the first database, made another one, reinstalled app. No difference.

It could be that I'm not completing a reinstallation properly. Maybe I need to enable something specific somewhere and haven't followed the documentation thoroughly.

Or it could be something else way beyond my ken.

So, here's a graphical list of symptoms.
Photos don't render.
Folders don't sort.
Smarty processor crashes.

1. App Environment after generic reinstallation.


2. Sync results: lots of photos in the database, no errors. The photos exist. Piwigo knows they exist, but doesn't render them.



3. No album photos at the top level.



4. No album photos, random album sort order, at 2nd level.



5. No photos rendering, random photo sort order at bottom level.



6. Another example of no rendering and random sorting at the bottom level.



7. Apply sort ordering to top level and subfolders. Nothing changed; the sort function doesn't work. Did this several times. Never made a change.



8. Drop down one album level to try sorting again. No change.



9. 2nd level album order after applying sort. Nothing has changed.



10. Go back up a level and apply automatic sorting. Didn't work. No change.



11. Looking at Batch manager - still no photos rendered.



12. A smarty error that shows up intermittently on various pages.


I have no idea what's going on here. Too complex for me to figure out.
Sorry that there is something so fundamentally wrong somewhere that I cannot get Piwigo to work.

Much appreciated, @erAck.

Have modified the php file, with no apparent effect, but will give it more time.

You've raised an interesting angle regarding permissions.
It seems possible that some other app has changed permissions on the NAS web folder, and barred access. For example, I put Dokuwiki on the same server a while back, and have had to set up ACS profiles. Maybe that's affected apps sitewide.
I'm going to change some permissions to see what happens.
