I am currently experiencing some permissions issues that I am unable to resolve after much reading of related posts and various attempts.

I am able to successfully install Piwigo in Docker (host computer is on macOS 26 with Docker and a number of other container running successfully) and create my first album and then upload photos to that album. At this point everything works as expected and there are no problems. As soon as I restart the host computer I get this error message:

Piwigo encountered an irrecoverable error
•/_data/templates_c no write access
#1 mkgetdir /var/www/html/piwigo/include/template.class.php(102)
#2 Template::_construct/var/www/html/piwigo/include/common.inc.php(294)
#3 include_once /var/www/html/piwigo/index.php(11)

I assumed it was a permissions issue of some sort and read the post by RushLana about setting UID and GID in the env file. Leaving the UID/GID blank or using 1000 for both I get the above error after a restart.

Checking the UID/GID for the user account on my host computer shows UID to be 502 and GID to be 20. If I put these values in the env file then I get this error as soon as I try to start Piwigo

Fatal error: Uncaught RuntimeException: The file could not be written to. Check that appropriate permissions have been set. in /var/www/html/piwigo/include/Logger.class.php:134 Stack trace: #0 /var/www/html/piwigo/include/Logger.class.php(306): Logger->open()#1/var/www/html/piwigo/include/Logger.class.php(295): Logger->write()#2/var/www/html/piwigo/include/Logger.class.php(202): Logger->og() #3 /var/www/html/piwigo/include/functions_user.inc.php(420): Logger->infoO#4/var/www/html/piwigo/include/functions_user.inc.php(302): getuserdata(#5 /var/www/html/piwigo/include/user.inc.php(137): build_user( #6

Environment details are:

• Piwigo 16.3.0 * Check for upgrade
• Installed on 18 April 2026, 11 minutes ago
• Operating system: Linux
• Container info: Official 16.3.0c
• PHP: 8.4.18 (Show info) [2026-04-18 15:09:01]
• MySQL: 11.8.6-MariaDB-ubu2404 [2026-04-18 15:09:01]
• Graphics Library: External ImageMagick 7.1.2-17
• Cache size N/A never calculated C Refresh

Piwigo URL: http://photos.bkc.ca

At this point I am unsure exactly where the error is. I previously had Piwigo installed on the same computer using a compose.yaml from linuxserver.io and it worked quite well for months. I am unable to figure out why the Piwigo official compose.yaml is causing these issues. My next step is to try the linuxserver.io yaml again

Any suggestions?

Hi,

Can you check the logs using docker logs ?

I'm looking for the line : "Non-bind-mount environment falling back to chmod o+rwx (expected on macOS and Windows, you can safely ignore setfacls warnings)"

Also how did you migrate from LinuxServer to the official container ? did you follow the migration guide ?
https://github.com/Piwigo/piwigo-docker … inuxServer

I don't have a Mac so I can't reproduce your bug easily.

brian.comeau@bkc.ca · 2026-04-20 17:02:04

Thank for the reply. Later today I will recreate the container with the Piwigo yaml and env file, restart and capture the Docker logs both before and after a restart.

To answer your question when I changed from linuxserver.io yaml to Piwigo yaml I completely deleted the entire container and started a new container with the Piwigo yaml and then reloaded the photos. To be very honest I am no longer 100% sure if my old yaml file came from linuxserver.io. I started with their yaml but tried a few others as I was evaluating everything. Since posting my question a day ago I deleted the Piwigo container and created a new container with my old yaml file from several months ago - this container does survives a restart unlike the Piwigo yaml

It will not take me long to recreate a Piwigo container, upload some photos and get you the information you have requested

brian.comeau@bkc.ca · 2026-04-22 05:18:02

occurred to me if you are checking mount points and permissions I decided to find out how to check folder permission inside a container. Ran the Inspect command and container ID. I have pasted in the 'Mounts' section for each container (not sure if this is any help or not)

Piwigo container

"Mounts": [
{
"Type": "bind",
"Source": "/Users/brian/piwigo/piwigo-data/piwigo",
"Destination": "/var/www/html/piwigo",
"Mode": "rw",
"RW": true,
"Propagation": "rprivate"
},
{
"Type": "bind",
"Source": "/Users/brian/piwigo/piwigo-data/scripts",
"Destination": "/usr/local/bin/scripts",
"Mode": "rw",
"RW": true,
"Propagation": "rprivate"
}

piwigo-db container

"Mounts": [
{
"Type": "bind",
"Source": "/Users/brian/piwigo/piwigo-data/mysql",
"Destination": "/var/lib/mysql",
"Mode": "rw",
"RW": true,
"Propagation": "rprivate"
}

RushLana · 2026-04-22 12:40:28

Hi,

The mounts aren't an useful info for this specific problem but can send me the logs from the main containers ?

Also if that's possible the output of ls -aln ./piwigo-data/piwigo ?

Hello,

I think I have what you have asked for...

If I go to the Docker Logs for the main Piwigo container I see this:

Thanks a lot for the logs, this will help reproduce the issue a lot faster.

While I work on it I can give you a quick fix, that should work until you restart your container.
You can run

Code:

docker exec -it <ContainerName> chown -R nginx:nginx /var/www/html/piwigo

Which will force all file within the piwigo-data/piwigo directory to be owned by the container nginx user.
It will prevent you from pasting files in the galleries directory without admin privilege.

I will keep you updated as I work to solve this.

brian.comeau@bkc.ca · 2026-04-23 23:34:10

Perhaps I don’t understand but I see the the reference to nginx in your last message - I do not use nginx but rather a Cloudflare tunnel to access Piwigo from outside my network (unless internally Piwigo uses nginx for some function) ??

RushLana · 2026-04-24 14:02:37

Hi,

The official piwigo container uses nginx internally, docker exec will run this command inside it.

brian.comeau@bkc.ca · 2026-07-08 06:37:40

Hello,

Just checking in see if there has been any progress in finding a fix for this issue?

Thanks…
